Does Lack Of B12 Degrade Your Eyesight?
I asked this question of Google AI and received this answer.
Yes, a lack of vitamin B12 can degrade your eyesight, typically by causing a condition known as nutritional optic neuropathy. This occurs because B12 is essential for maintaining a healthy nervous system, and a deficiency can damage the optic nerve, which transmits visual information from the eye to the brain.
Here is how a B12 deficiency can impact your eyes and vision:
Optic Neuropathy: A, often painless, progressive, bilateral, and symmetrical reduction in visual acuity.
It often results in blurred or disturbed vision, central or cecocentral scotomas (blind spots), and reduced color vision.
Vision Loss: Severe, long-term B12 deficiency can lead to permanent vision loss if not treated promptly.
Retinal Damage: B12 deficiency can cause retinal hemorrhages (bleeding in the retina), known as Roth’s spots.
Eye Movements: In rare cases, it can cause involuntary eye movements (nystagmus) or uncontrollable eye twitching.
Dry Eye Disease: Some evidence suggests B12 deficiency can cause severe dry eye issues and pain.
Reversibility
Vision problems caused by B12 deficiency are often reversible with prompt treatment.
However, if the damage is allowed to become chronic, the vision impairment can be permanent.
Risk Groups
Those at higher risk of B12 deficiency leading to vision issues include:
- Strict vegetarians and vegans.
- Older adults (60+).
- Individuals with pernicious anemia.
- People with gastrointestinal conditions (Crohn’s disease, celiac disease) or who have had weight-loss surgery.
I am in two of these groups, as I’m 78 and coeliac.
My First Eye Test
This was performed in about 1993, by a friend’s father, who was a retired Senior Eye Surgeon from Heath Road Hospital in Ipswich.
At the time, I wasn’t coeliac.
He said, that I’d got the driest eyes he’d ever seen. I actually told my last GP, so it may be in my notes.
Misearable Weather And My Eye Sight
In January, I wrote this post called Does Miserable Weather Deplete Your B12?
Is this why my eyes and especially my left eye, have been bad ladely?
Eating To Raise My Vitamin B12
Is My B12 Level Low?
Consider.
- The Weather Isn’t B12-Friendly As I found Out In Does Miserable Weather Deplete Your B12?
- My brain seems to hoover up any B12 it can find for its own purposes.
- I am getting signs in my body like red feet, pine-and-needles, which Google AI tells me could be low be a sign of B12.
I am not surprised my B12 is low.
B12 Rich Foods
Typing “B12 Rich Foods” into Google AI gave me this.
Vitamin B12-rich foods are primarily animal-based, with clams and beef liver offering the highest concentrations. Other excellent sources include fish (salmon, trout, tuna, sardines), red meat, eggs, dairy products (milk, yogurt, cheese), and poultry. Vegetarians and vegans can find B12 in fortified foods like nutritional yeast, plant milks, and breakfast cereals.
I’ll now go through each food in order.
- Clams – Never tried them, but I’m not a great lover of shellfish! – My biggest client did poison himself on oysters in the City.
- Beef Liver – Love it!
- Fish (Salmon, Trout, Tuna, Sardines) – No Problem!
- Red Meat, Eggs – No Problem!
- Dairy Products (Milk, Yogurt, Cheese) – No Problem! – I’ve only eaten yoghurt in the last few years.
- Poultry – No Problem!
I think I can increase my B12 intake with foods I like.
I often eat two small pots of yoghurt a day, with the second with a punnet of strawberries.
Smoked Salmon Also Seemsw Good For My Diverticular Disease.
I’ve just got to watch what I eat!
But I have Seen Worse Diets
Is Smoked Salmon Good For Uncomplicated Pancolonic Diverticular Disease?
For lunch today, I made myself a sandwich with a 100 gram pack of Mark’s and Spencer’s smoked salmon.
Out of curiosity, I asked Google AI. “Is there any B12 in smoked salmon” and received this reply.
Yes, smoked salmon is an excellent source of vitamin B12. A 100-gram (3.5-ounce) serving provides over 100% of the daily recommended value, with some studies showing as much as 136% (roughly 3.3µg) of the daily intake. It is considered a rich source of B12 along with other nutrients like omega-3 fatty acids, protein, and vitamin D.
Key details regarding B12 in smoked salmon include:
High Concentration: A 3-ounce serving provides approximately 2.8 micrograms of vitamin B12.
Daily Needs: Consuming 100g of smoked salmon can fulfill 136% of the daily requirement for vitamin B12.
It looks like a pack of smoked salmon can provide my daily needs of B12.
I followed up, by asking Google AI, the question in the title of this post.
This was the answer that I received.
Smoked salmon can be a suitable protein choice for managing uncomplicated diverticular disease, particularly during periods when a low-fiber or moderate-fiber diet is recommended to manage symptoms. It is generally considered a lean, high-quality protein source.
However, the suitability of smoked salmon depends on the status of your condition:
During a Symptom-Free Period (General Diverticulosis):A healthy, balanced, high-fiber diet is recommended, and fish like salmon is a good choice.
During a Symptom Flare (Uncomplicated Diverticulitis):
A low-fiber, low-residue diet is typically recommended to allow the colon to rest.
Smoked salmon is generally acceptable as a soft, easy-to-digest protein source in this phase.
Important Considerations:
Smoked salmon is a processed meat (smoked/cured), and some guidelines advise limiting processed meats as they may contribute to inflammation,
or at least suggesting they should not be consumed frequently compared to fresh, white fish
Key Recommendations:
Include in a balanced diet:
It can be part of a healthy diet, for example, with low-FODMAP foods.
Watch for Sodium:
Smoked salmon can be high in salt, so moderate consumption is advised.
Focus on Lifestyle:Overall, a high-fiber diet (when not in a flare), plenty of water, and avoiding smoking are the best ways to manage diverticular disease.
It looks from this, that smoked salmon in moderation should be OK.
Disappearance Of Biological Sex In Research ‘Is Like Stalin-Era Purge’
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Sir Anthony Finkelstein, a university vice-chancellor, laments that the category has become ‘politically uncomfortable’
These three paragraphs add detail to the post.
A university vice-chancellor has warned of the “quiet disappearance” of sex as a recorded variable in academic research, likening pressure to abandon politically sensitive classifications to Stalin-era persecution of statisticians.
According to Times Higher Education, Sir Anthony Finkelstein, head of City St George’s, University of London, made the remarks at an event to discuss the Sullivan review, which recommended that biological sex be used as the default category in research data collection.
Finkelstein said it was essential that researchers retain established classifications for sex in their statistical analysis. He said: “In recent years, there’s been growing unease about recording sex as a basic variable, and pressure — sometimes explicit and sometimes ambient — to replace it with or collapse it into gender identity.”
I fund and participate in medical research and certainly wouldn’t do so, if I felt the research was not being conducted in a scientifically-correct manner.
Do Coeliacs Suffer Badly From Sepsis?
As everybody seems to be getting this these days, I just had to ask Google AI the question in the title of this post.
This is the reply I received.
Sepsis Outcome: While celiac patients are more likely to get sepsis, studies indicate that celiac disease does not significantly influence the survival or prognosis once a patient has developed sepsis.
Are There Some People Who Lose Their B12 Very Quickly?
Many years ago in Suffolk, I was sure, that my three-monthly B12-injection wasn’t done correctly.
It was by a trainee, so I told my GP and she may have repeated the injection. Perhaps the trainee missed the muscle or something?
I’m not sure, but I may have had a repeat injection.
I had another B12 injection about ten days ago and twice in the last two days, I have had symptoms that could be low B12 levels.
Yesterday at one point, I thought I was having a stroke, but a hot bath seemed to improve things.
I then found a Marks & Spencer Liver & Bacon meal-for-one and cooked it, but just eating the Liver & bacon.
I seemed to do the trick.
Today, coming home with shopping, my left leg was painful and so I asked Dr. Google AI for some advice.
I asked if “If low B12 is connected to red feet” and received this answer.
Low vitamin B12 is strongly connected to foot issues, primarily causing peripheral neuropathy that manifests as burning sensations, numbness, tingling (“pins and needles”), and sometimes, color changes like redness, purple, or white due to reduced blood flow or nerve damage. It causes nerve damage, which can lead to painful or “burning” feet.
Key Connections Between B12 Deficiency and Foot Symptoms:
Peripheral Neuropathy: A, the lack of B12 damages the myelin sheath covering nerves, resulting in burning, numbness, or tingling in the feet.
Reduced Blood Flow/Color Changes: Deficiency can lead to, significantly colder feet that may appear red, white, or purple due to impaired circulation.
Painful Sensations: Often described as a burning feeling, which can make feet feel hot or tender.
Muscle Issues: Weakness, cramping, and poor coordination can affect mobility.
Note:
- I certainly had pins and needles in my hands, yesterday.
It certainly, looked to me that I might have had low B12.
Trump May Have Alzheimer’s, Says Niece
The title of this post, is the same as that of this article in The Times.
This is the sub-heading.
Mary Trump said the president appeared to have developed a ‘deer-in-the-headlights look’ that reminded her of his late father, Fred Trump.
These three paragraphs add detail to the story.
President Trump’s niece has suggested her uncle could be suffering from Alzheimer’s based on a “deer-in-the-headlights” expression that reminds her of the president’s father.
Mary Trump, a longtime critic of her uncle, said she saw flashes in him of Fred Trump, her grandfather, who she witnessed struggle with the degenerative disease before his death aged 93 in 1999.
“Sometimes it does not seem like he’s oriented to time and place,” Mary Trump, 60, told New York Magazine of her uncle. “And on occasion, I do see that deer-in-the-headlights look.”
Fifteen years ago, my consultant at Addenbrooke’s said I should go on Warfarin (rat poison) to thin my blood. But my GP said I should stick to a small aspirin every day.
The result was that I had a serious stroke on holiday in Hong Kong.
Luckily, I made a remarkable recovery and I am now testing a Warfarin replacement drug, which is two pills a day and no testing, except by the doctors every three months.
My current cardiologist has even used the GP’s actions in a lecture to students on how not to behave.
Trump is playing with fire!
Surely he should at least be taking Warfarin and being tested frequently.
If any cardiologists are reading this, they should note, that I am coeliac and for the last twenty-eight years, I have been having regular B12 injections.
As B12 injections are used in Trumpland to help stroke patients recover, but not in the UK, from observations of my own recovery, by several doctors, I am tempted to believe that B12 injections may help stroke recovery.
Any sensible offer to help in research will be considered.
From my own experience, an affordable drug, like B12 injections could have a place in stroke recovery.
To get a second opinion, I asked Google AI, this question. – “Do Vitamin B12 Injections Help With Stroke Recovery?”
I received this answer.
Vitamin B12 injections may aid stroke recovery, particularly for individuals with a deficiency, by supporting nerve function, reducing homocysteine levels, and enhancing neurological rehabilitation. Research indicates that adequate B12 levels are crucial for protecting the brain after an ischemic stroke.Key findings regarding Vitamin B12 and stroke recovery:
- Neuroprotection: Vitamin B12 aids in maintaining myelin sheaths, which are essential for nerve repair and protecting the central nervous system after a stroke.
- Reduced Damage: Studies suggest that B12 can help reduce cerebral injury and improve long-term neurobehavioral function.
- Correcting Deficiency: People with B12 deficiencies often have worse stroke outcomes, making correction via injections crucial.
- Homocysteine Control: B12 helps lower homocysteine, a risk factor for vascular damage and recurrent stroke.
- Efficiency of Injection: For those with absorption issues (e.g., older adults or those with GI issues), injections bypass the digestive system to ensure maximum absorption.
The NHS will face a lot of resistance, if they want to take away my B12 injections.
Does Miserable Weather Deplete Your B12?
Consider.
I have been feeling down this winter and especially in the last few weeks.
- My three-monthly B12 injection is now due.
- But I can’t get one until the second of February.
- But on miserable days like this, I do feel bad.
- So I have asked for the injection to be moved forward?
In answer to my question in the title of this post, Google AI gave this answer.
Yes, cold, dark, and “miserable” winter weather can contribute to lower Vitamin B12 levels, or at least worsen an existing deficiency.
While miserable weather does not directly “burn” B12 out of your body, the associated lifestyle changes and reduced sunlight can cause levels to drop.
Here is how winter weather affects B12:
Reduced Sun Exposure:
While Vitamin D is directly linked to sunlight, the general reduction in sunlight during winter can affect energy levels and mood.
Low Vitamin B12 can also cause similar symptoms, making it harder to distinguish between a vitamin deficiency and “winter blues”.
Dietary Changes:
In winter, people may consume less of the fresh, nutrient-dense foods (like animal products) that are high in B12, or they may feel less motivated to maintain a balanced diet, leading to lower intake.
Increased Stress and Fatigue:
Cold, dark weather can induce stress.
Chronic stress and fatigue are known to deplete B vitamin reserves, including B12.
Increased Sensitivity to Cold: Ironically, if you are already slightly deficient in B12, you may feel much colder, more tired, and more lethargic than others, exacerbating the feeling of “miserable” weather.
Key Takeaways:
Check Levels: If you experience extreme fatigue, low mood, or numbness in your hands and feet during winter, it might be worth checking your B12 levels.
Supplementation: In many cases, people, especially vegetarians or vegans, find that B12 supplements or injections help manage symptoms of low energy and poor mood during colder months.
Diet: Ensure you are getting enough B12-rich foods like meat, fish, dairy, and fortified foods.
If you are feeling significantly lower energy or mood during winter, it is always best to consult a healthcare professional.Conclusion:
Do B12 Injections Help Stroke Recovery?
A friend, who thinks I’ve made a good recovery from a stroke, asked me if there is anything I could recommend, for another of his friends, who has just had a stroke.
As a coeliac, am I in a group with a higher risk of a stroke?
So, I asked Google AI, the question, if this were true and received this answer.
- Initial Higher Risk: Some studies suggest a slightly increased risk of stroke (roughly a 10-15% increased likelihood). This risk is highest in the first year after diagnosis.
- Effect of Gluten-Free Diet: After 5 years on a strict, gluten-free diet, the risk of stroke for people with coeliac disease is virtually the same as that of the general population.
- Overall Risk: While some studies have suggested a link, others, including a 2023 UK Biobank study, found no clear evidence of an association between coeliac disease and stroke, although they did find an overall increased risk of cardiovascular disease (27% higher).
- Mechanism: The potential for a higher risk is likely due to the chronic inflammation associated with untreated coeliac disease, rather than traditional risk factors like high blood pressure or smoking.
- Children: A 2023 study found that coeliac disease plays a minimal role in the risk of stroke in children, but recommended that doctors consider it a potential factor in cases of stroke with unknown causes.
Conclusion:
While untreated coeliac disease may slightly increase the risk of stroke due to chronic inflammation, adhering to a gluten-free diet helps manage this risk.
This study by coeliacUK and Oxford University, was the source of the findings by Google AI.
Do B12 Injections Help Stroke Recovery?
For nearly thirty years, ever since I was diagnosed as coeliac, I have had regular three-monthly B12 injections. So ever since my stroke in 2011, I have had B12 injections.
So now AI is available, I felt I should ask Google AI to see if it says anything useful.
This is the answer I received.
- Nerve Repair & Axonal Growth: B12 aids in repairing damaged nerve fibers (axons) and regenerating nerve cells, vital for restoring lost function after a stroke.
- Reduces Inflammation: It helps calm the harmful inflammatory response (neuroinflammation) in the brain after an ischemic stroke, notes this ScienceDirect article.
- Improves Brain Communication: B12 supports neurotransmitter production, allowing brain cells to communicate more effectively and speeding up healing, according to this Flint Rehab article.
- Lowers Stroke Risk: By reducing homocysteine levels, an amino acid linked to stroke, B12 can help prevent recurrent strokes, reports this Flint Rehab article and this NIH article.
- Supports Microglia Function: It helps functionalize microglia (brain immune cells) to reduce injury and promote recovery, states this ScienceDirect article.
- To Boost Recovery: For those with moderate deficiencies, injections or supplementation can improve neurological function, notes this NIH article.
Conclusion
B12 injections seem to have done me no harm.
I also have them on the NHS, at no cost to myself.
If the NHS said I couldn’t have them, I’d pay for them.
What Are Gail’s Like For Gluten-Free Food
As a coeliac, I just had to ask this question of Google AI and I choose Gail’s as my first test.
This was the answer.
Gail’s offers a standout, award-winning Gluten-Free Sourdough, made in a separate facility for purity, but for other items, cross-contamination is a risk, as they use shared equipment and ingredients. While they have gluten-free salads, flourless cakes, and sometimes other specials, customer experiences vary widely, with some finding staff knowledgeable and careful, while others report poor communication and lack of safe options for severe allergies like Coeliac disease, so always check ingredients and ask staff about specific items.
I think I’ll stay clear.
