The possible clinical causes of very little meat on the buttocks include decreased fat in the buttocks, decreased elasticity of the buttock muscles, atrophy of the buttock muscles, and hereditary factors. 1. Decrease in buttock fat: some people have excessive dieting or malnutrition, which will make the body’s intake of calories decrease and lead to a decrease in body fat synthesis. 2. Decrease in elasticity of hip muscles: ageing and decrease in hormone level will lead to decrease in muscle elasticity and sagging of hip, which will make the buttocks look like less meat. 3. Atrophy of gluteal muscles: clinically common herniated lumbar intervertebral discs, paraplegia, paraplegia, etc., will cause damage to the gluteal nerves, and the gluteal muscles are not strong enough to atrophy, which will lead to the above situation. 4. Hereditary factors: some people may be born with less fat in the buttocks and lower muscle density, thus less meat is observed on the appearance, but this is a normal physiological phenomenon, and is also a differentiated characteristic of individuals. It is recommended that people with this kind of condition should deal with the original disease and go to the hospital as soon as possible for consultation and treatment.
