Most people who stop metformin do not stop because it failed. They stop because of the first two weeks. Metformin works mainly on your liver, but a large amount of the drug stays in your intestine and sits there in high concentration. That is where the nausea, the cramping and the diarrhoea come from. It is a local effect, not the drug poisoning you, which is why the fixes are practical. Taking it with food slows the exposure. Starting low and increasing gradually gives your gut time to adapt. And the extended release form spreads delivery out instead of dumping it all at once, which many people tolerate far better. Most of this settles within a few weeks. One side effect is slower and quieter. Long term use can reduce vitamin B12 absorption, and low B12 causes fatigue and tingling in the hands and feet, which often gets blamed on diabetes itself. That is why levels get checked periodically. 🧠⚡ If the early side effects are making it hard to continue, that is a conversation about dose or formulation rather than a reason to stop on your own. And metformin is usually paused during severe illness, significant dehydration, or before certain scans, because those are the situations where it can build up. Follow that advice if you are given it. #Explainique #Metformin #Type2Diabetes #Pharmacology #MedEd

You can eat plenty of vitamin B12 and still end up deficient. Of every vitamin, this one has the most fragile route into your body. B12 arrives bound to protein in food, and stomach acid has to release it. Your stomach then makes a separate protein called intrinsic factor, which escorts it down, and only at the very end of your small intestine can the pair be absorbed. Break any link in that chain and the vitamin goes straight through you. That is why deficiency shows up with low stomach acid, with acid suppressing medication, with metformin, after stomach or bowel surgery, and in people eating no animal products. B12 has two jobs that matter. It builds red blood cells, and it maintains the insulating sheath around your nerves. So shortage starts as fatigue and becomes tingling in the hands and feet, balance problems and memory trouble. 🧠⚡ #Explainique #VitaminB12 #B12Deficiency #Nutrition #MedEd

Glaucoma can take a large share of your vision before you notice anything is wrong. The reason is where it starts and how your brain handles it. Your eye continuously produces a clear fluid and continuously drains it away. When drainage slows, pressure inside the eye rises. That pressure presses on the optic nerve, the cable carrying every image to your brain, and the fibres begin to die. The fibres at the edge go first, so vision is lost from the periphery inward. That is where your brain does you no favours. It fills in the missing edges using the other eye and what it expects to be there, so the gaps feel like nothing. By the time someone notices, significant nerve has already been lost, and nerve does not grow back. Treatment lowers the pressure to protect what remains. 🧠⚡ This is why glaucoma is found at eye exams rather than by symptoms. Get them on schedule, and sooner if glaucoma runs in your family. One exception needs naming. Sudden severe eye pain with headache, nausea, blurred vision and halos around lights is a different form and an emergency, so that is same day care rather than waiting it out. #Explainique #Glaucoma #EyeHealth #VisionLoss #MedEd
