Hello everyone,

Today, I would like to delve into a topic that has been a concern for many individuals who have undergone bariatric surgery – hair loss. This phenomenon, while not life-threatening, can be emotionally distressing and often leads to questions like Why do bariatric patients lose their hair? and Is there a way to prevent it?

Firstly, it’s important to understand that hair loss after bariatric surgery is quite common and usually temporary. It typically starts 3-6 months post-surgery and can last up to a year. This condition, known as telogen effluvium, is triggered by the physiological stress the body undergoes during and after the surgery, coupled with drastic changes in diet and nutrient intake.

Bariatric surgery, such as gastric bypass or sleeve gastrectomy, often results in a significant reduction in calorie intake. This sudden decrease can shock the body into a survival mode, where it conserves energy by diverting nutrients away from non-essential functions like hair growth. As a result, more hair follicles enter the resting phase (telogen) prematurely, leading to increased hair shedding.

Moreover, nutrient deficiencies, particularly of protein, iron, zinc, and vitamins (especially B12 and D), can contribute to hair loss. Bariatric surgery can affect the body’s ability to absorb these nutrients due to alterations in the digestive system. Therefore, even if patients are consuming adequate amounts, they may not be absorbing them effectively, leading to deficiencies.

Furthermore, hormonal changes post-surgery can also play a role in hair loss. Bariatric surgery can lead to changes in levels of hormones that regulate hair growth and shedding, such as thyroid hormones, cortisol, and sex hormones.

Now, the question arises – how can this be prevented or managed?

Firstly, it’s crucial to maintain a balanced diet rich in essential nutrients. Protein is particularly important as it’s the building block of hair. Bariatric patients should aim for 60-80 grams of protein daily. Iron, zinc, and vitamins should also be included in the diet or taken as supplements, as advised by the healthcare provider.

Secondly, regular follow-ups with the healthcare team are essential to monitor nutrient levels and adjust supplementation as needed.

Lastly, stress management techniques, such as meditation, yoga, or counseling, can help cope with the emotional stress of surgery and potential hair loss.

In conclusion, while hair loss post-bariatric surgery can be distressing, understanding its causes and implementing appropriate dietary and lifestyle modifications can help manage this condition. Remember, it’s always important to consult with your healthcare provider before making any significant changes to your diet or supplement regimen.
