Temporary hair loss is a common side effect following weight loss surgery, also known as bariatric surgery. This condition is known as telogen effluvium, and it usually occurs within the first six months after the surgery.

During bariatric surgery, the body undergoes significant changes, including a drastic reduction in calorie intake, changes in hormonal levels, and changes in the absorption of nutrients. These changes can result in hair follicles entering the resting phase of their growth cycle (known as the telogen phase), which can lead to hair shedding.

While telogen effluvium can be distressing, it is usually temporary and hair growth typically resumes within a few months. To help reduce the risk of hair loss following weight loss surgery, it’s important to maintain a healthy and balanced diet, take vitamin and mineral supplements as recommended by your healthcare provider, and avoid crash diets or rapid weight loss. Additionally, gentle hair care practices such as avoiding heat styling tools and using a wide-tooth comb can help reduce hair breakage.
