If you’ve noticed more hairs in your brush since starting metformin, you’re not alone, and it’s a valid concern. Many women managing conditions like PCOS or type 2 diabetes with this medication wonder if it’s the cause of their hair thinning. It can be worrying when something meant to help your health seems to have an unexpected side effect.
Let’s untangle the connection between metformin and hair loss. The relationship isn’t always straightforward, and understanding the potential reasons can help you have a more informed conversation with your doctor.
The Surprising Link Between Metformin and Your Hair
Interestingly, metformin itself is rarely the direct culprit. Instead, the link is often indirect. One of the most common reasons involves a vitamin deficiency. Metformin can lower the body’s levels of vitamin B12 over time. Since B12 is crucial for healthy cell growth, including the cells that make up your hair follicles, a significant deficiency can lead to hair shedding. This type of hair loss is usually temporary and can be addressed.
Is It the Medication or Your Underlying Condition?
It’s also important to consider the conditions metformin is used to treat. For women with Polycystic Ovary Syndrome (PCOS), hair loss is a frequent symptom due to hormonal imbalances. When you start metformin, it can take time for your hormones to regulate. The initial shedding you see might actually be your body’s response to this shift, not the drug itself. Similarly, the physical stress of a new diagnosis or poorly managed blood sugar can also trigger temporary hair loss.
What to Do If You’re Worried About Hair Thinning
First and foremost, do not stop taking your medication without speaking to your healthcare provider. Suddenly stopping metformin can be dangerous. Instead, schedule an appointment to discuss your concerns. Your doctor can order a simple blood test to check your B12 levels and rule out other common causes of hair loss, like thyroid issues or ferritin (iron) deficiency.
If a B12 deficiency is found, supplementation often helps. Focusing on a nutrient-rich diet and managing stress can also support overall hair health. Remember, for many women, this is a temporary phase as their body adjusts.
While seeing hair loss can be distressing, it’s often a manageable side effect. By working with your doctor to find the root cause, you can take steps to support your hair’s health while continuing the important benefits of your metformin treatment.
