Studies have also shown that zinc supplement can help hair regrowth due to its role in protein and nucleic acid synthesis in hair follicles and other body cells. A study found a low serum zinc concentration in 312 patients with hair loss compared to controls. a leads to thinning of the hairs and subsequent shedding. Researchers have shown that nutritional deficiencies shorten the anagen phase causing a large number of hairs to enter telogen at the same time. Following gastric sleeve surgery, patients must be encouraged to take more protein in order to prevent a deficiency state. Keratin is a protein rich in disulfide bonds, and deficiency of sulfur-containing amino acids such as cysteine and methionine leads to the formation of brittle and fragile hairs and subsequent shedding. Protein malnutrition is one of the causes of hair loss. Why hair loss after gastric sleeve surgery If however many hair follicles enter the resting stage at the same time, shedding may ensue at the end of the resting phase (3months), a condition known as telogen effluvium. Up to 100 hairs may shed from the scalp on a daily basis in a healthy individual.Įach hair follicle undergoes its cycle independent of others. On the head, anagen may continue for five years, the catagen phase lasts for two weeks, while telogen takes about three months. The length of these phases varies from one part of the body to another. ![]() Telogen is the resting phase at the end of which the club hair is shed off. During this phase, nascent hair is under development. Catagen is the phase of conversion from active growth to resting phase. The anagen is the phase of active hair production. The cycle consists of 3 phases: anagen, catagen, and telogen. Keratin is a fibrous protein that is insoluble in water and organic solvent and rich in sulfur-containing amino acids.Įach hair follicle undergoes a growth cycle. ![]() It grows out of the hair follicle (hair bulb) which is located in the dermis and extends to the skin surface. In this group of people, hormonal and psychological stress may also be responsible for hair loss. Micronutrient deficiencies may, however, occur due to inadequate intake rather than poor absorption. Patients with gastric sleeve surgery have a low incidence of hair loss as the surgery is purely restrictive with no malabsorptive components. Preoperative hair density and a male pattern of hair loss before surgery may significantly influence the quantity of hair loss. The degree of hair loss differs from patient to patient. ![]() The surgery itself is a stressful condition that is accompanied by various hormonal responses, which in addition to the physical and psychological stress of bariatric surgery, may affect hair growth. However, it is temporary starting about 3months after the procedure and lasting for about 3-6months. It is often associated with deficiencies in protein and micronutrients such as zinc and iron. Hair loss following bariatric surgery can occur in up to 41% of patients. Many complications are associated with this group of surgeries. Weight loss is achieved via a reduction in food intake as a result of small stomach and early satiety. The size of the stomach is reduced to one-fifth of its original size. It is often done by laparoscopic approach. ![]() Gastric sleeve surgery is one of the restrictive bariatric (weight loss) surgeries available for the treatment of morbid obesity.
