What are the purple stripes on the inner thighs?

The purple stripes on the inner thighs are also known as atrophy stripes or stretch marks. Initially, they appear as light red or light purple and gradually turn white over an extended period, which is a common issue for many people. Besides the thighs, these stripes also tend to appear on areas with more fat, such as the abdomen, chest, and waist. Generally, they do not cause symptoms like itchiness or pain and do not require specific treatment, but more attention should be paid to daily skin care to prevent their proliferation. So, what causes the purple stripes on the inner thighs? Here are the reasons:

1. Poor skin elasticity and ruptures in subcutaneous tissue fibers can lead to purple stripes on the inner thighs. This is closely related to chronic skin diseases or the loss of skin nutrients.

2. Diseases such as Cushing's syndrome can cause excessively high levels of adrenal glucocorticoids, affecting the secretion of elastin in skin fibers, leading to skin ruptures and purple stripes.

3. Excessive obesity is also one of the significant factors contributing to purple stripes on the inner thighs. As subcutaneous fat increases, the elastic fibers of the skin continue to expand, and once ruptured, purple stripes appear.

4. Drug factors, such as long-term use of corticosteroid medications, can affect dermal cells, thereby increasing the incidence of atrophy stripes.

These are the primary factors causing purple stripes on the inner thighs. Patients in such situations can apply topical medications locally under a doctor's guidance. They can also consume foods rich in protein and vitamins to supplement the nutrients lacking in their bodies. It is also important to strictly control body weight, avoid excessive obesity, refrain from sitting for too long, appropriately relieve pressure on the lower limbs, and prevent the proliferation of atrophy stripes.
