If you’ve noticed more hair in your brush since starting metformin, you’re not alone. It’s a concern that many people managing their blood sugar levels bring up. Metformin is a cornerstone medication for type 2 diabetes and PCOS, but its potential side effects can be worrying. Let’s look at what might be happening with your hair.
The Surprising Link Between Metformin and Hair
Interestingly, metformin itself is not directly listed as a common cause of hair thinning. However, the connection is more nuanced. One of the leading theories points to a vitamin deficiency. Long-term use of metformin can sometimes interfere with your body’s ability to absorb vitamin B12. Since B12 is crucial for healthy cell growth, including the cells that make up your hair follicles, a deficiency can lead to hair that looks thinner or grows more slowly.
Could It Be Your Underlying Health Condition?
Before placing the blame solely on the medication, it’s important to consider the conditions metformin is used to treat. Both type 2 diabetes and PCOS can directly contribute to hair loss. Fluctuating blood sugar levels can affect nutrient delivery to hair follicles. With PCOS, hormonal imbalances are a well-known culprit for hair thinning. Sometimes, starting a new medication simply coincides with a pre-existing issue becoming more noticeable.
What You Can Do About It
If you’re experiencing hair thinning, the most important step is to talk to your doctor. Never stop taking your prescribed medication without their guidance. They can perform a simple blood test to check your B12 levels and determine if a deficiency is the root cause. If it is, a B12 supplement or dietary adjustments may be recommended. Managing your underlying condition effectively with metformin can also improve your overall health, which may, in turn, benefit your hair in the long run.
While seeing changes in your hair can be distressing, it’s often a manageable issue. By working with your healthcare provider, you can identify the true cause and find a solution that keeps both your health and your hair in good condition.
