What is bariatric surgery?

Bariatric surgery refers to a group of medical procedures aimed at helping individuals lose weight by altering the digestive system's anatomy and functionality. This is typically achieved by reducing the size of the stomach, re-routing the digestive tract, or a combination of both. 

Bariatric surgery is usually considered for individuals who are severely obese or those who have obesity-related health conditions and have not achieved long-term weight loss success with other methods.

There are several types of bariatric surgeries, including:

  • Gastric bypass (Roux-en-Y Gastric Bypass): This surgery involves creating a small pouch at the top of the stomach and connecting it directly to the small intestine, bypassing a significant part of the stomach and the first section of the small intestine.
  • Sleeve gastrectomy: This procedure involves removing a large portion of the stomach, leaving a smaller, banana-shaped section that can hold less food.
  • Adjustable gastric band (Lap-Band): A band is placed around the upper part of the stomach to create a small pouch. The size of the opening from the pouch to the rest of the stomach can be adjusted by filling the band with saline.
  • Biliopancreatic diversion with duodenal switch (BPD/DS): This is a two-part procedure that begins with the removal of a portion of the stomach, similar to a sleeve gastrectomy. The second step involves re-routing the small intestine to bypass a significant portion, reducing calorie and nutrient absorption.

Why hair loss after bariatric surgery occurs

Hair loss after bariatric surgery, often termed "telogen effluvium," is a common side effect experienced by many patients. This temporary hair thinning happens due to several interrelated reasons:

  • Rapid weight loss: After bariatric surgery, the body undergoes a significant and swift weight reduction. This sudden change can cause a stress response, pushing more hair follicles into the resting phase, which can eventually lead to increased hair shedding.
  • Nutritional deficiencies: Bariatric surgery alters the digestive system, which can impact the body's ability to absorb essential nutrients. Deficiencies in protein, iron, zinc, biotin, vitamin D, and other vitamins and minerals are known to affect hair health. Without these vital nutrients, hair can become weak, brittle, and may fall out more than usual.
  • Hormonal changes: The surgery can lead to fluctuations in hormones, especially with the rapid changes in body composition and fat storage. These hormonal shifts can influence the hair growth cycle.
  • Reduced caloric intake: Post-surgery, patients are often on a very restricted diet, which can decrease overall caloric intake. The body may prioritize vital functions over hair growth, leading to hair thinning.
  • Medications and anaesthesia: Some medications prescribed after surgery, as well as the effects of anaesthesia, can contribute to hair loss.
  • Physical stress of surgery: The surgery itself, irrespective of weight loss, represents a significant physical stress to the body. Stress is a known trigger for hair loss.
