It is well known that metformin can cause diarrhoea and this is one of the most common side effect that people experience (The Prevalence of Chronic Diarrhea Among Diabetic Patients). It should ‘settle’ after starting on the medication. But what if it doesn’t? What does ‘settle’ actually mean and how do you know if you should continue taking it? Also, why should you actually take something which causes such symptoms?
Metformin is a type of medication used to treat high blood glucose level in people with type 2 diabetes. It comes in the form of a pill with some brand names including Diabex, Glucophage, and Diaformin. It is often the first drug to be prescribed to people with diabetes. Metformin can also be used in women with gestational diabetes and polycystic ovary syndrome.
Another common side effect of metformin use is vitamin B12 deficiency. Vitamin B12 has many important functions in our bodies. It’s needed to help make new blood cells and help our brain and nervous system to function properly.
Metformin can interfere with the absorption process of vitamin B12, which can cause people with diabetes to become deficient in B12. If you haven't been tested for B12 deficiency, request a blood test next time you see your doctor. Treatment for vitamin B12 deficiency is super simple and includes either a intramuscular injection or oral supplementation. Your doctor will choose the best treatment option for you.

So, I guess by now you are wondering
why on earth you should take Metformin at all…
It is actually a really good medication that works not only to help regulate blood glucose levels but also decreases the amount of insulin you need. Slowing the actual progression of diabetes, it has also been linked to other health benefits such as reducing cardiovascular events such as heart attacks and strokes; lowering cholesterol levels and even protecting against cancers. For more information please refer to Benefits of Metformin.
Studies indicate that it should be the drug of first choice on diagnosis of type 2 diabetes for very good reasons (American Diabetes Association: Approaches to Glycemic Treatment). When someone is given the diagnosis of diabetes, metformin is the first oral drug to be prescribed alongside lifestyle interventions, including changes in diet and physical activity levels. It is also used in pre-diabetes, gestational diabetes and polycystic ovarian syndrome and is considered a safe medication to take with few side effects other than those affecting the gut.
It is important therefore to first weigh up the pros and cons of taking metformin and talk to your doctor before stopping it to ensure you are making the best choice for your diabetes and general health. It may be as simple as a reduction in dose or changing brands to make a real difference.
