肚皮痒是怎么回事

In general, itchy abdomen may be caused by factors such as dry skin, abdominal skin stretching during pregnancy, eczema, psoriasis, or diabetes. It is recommended to seek timely medical attention, identify the underlying cause, and receive symptomatic treatment under the guidance of a qualified physician. Specific analyses are as follows:

1. Dry Skin

When the skin is dry, its barrier function is compromised, making it more susceptible to external irritants and leading to itching, including on the abdominal area. Regular application of moisturizing lotions or creams is recommended to maintain skin hydration.

2. Abdominal Skin Stretching During Pregnancy

During pregnancy, rapid expansion of the abdomen places significant tension on skin fibers, which can lead to tearing and subsequent itching. Additionally, hormonal changes may affect skin condition and exacerbate itchiness. Pregnant individuals may use skincare products rich in vitamin E and collagen to help maintain skin elasticity, or gently massage the abdominal area to promote blood circulation.

3. Eczema

Eczema may be triggered by environmental factors or exposure to allergens. It damages the skin’s barrier function, increasing sensitivity to external stimuli, while the inflammatory process itself causes itching—commonly affecting areas such as the abdomen—and may be accompanied by symptoms like redness and swelling. Treatment may include medications such as miconazole and clobetasol cream, azithromycin tablets, or desonide cream, used according to medical advice.

4. Psoriasis

Psoriasis may result from genetic, infectious, or immune-related factors. In patients with psoriasis, the immune system mistakenly attacks skin cells, accelerating their growth cycle and causing excessive accumulation of skin cells that form scaly plaques, resulting in itching on areas such as the arms, face, and abdomen. Symptoms may also include joint pain, fatigue, and red patches covered with silvery-white scales. Treatment options under medical supervision may include tripterygium glycosides tablets, acitretin capsules, or cyclosporine capsules.

5. Diabetes

Diabetes may be caused by genetic predisposition, poor diet, and other factors. When blood glucose is poorly controlled, the high-sugar environment can damage nerves and microvessels, reducing blood supply to the skin and leading to abnormal sensations and itching—commonly affecting the face, limbs, and abdomen. Patients may also experience symptoms such as increased thirst, frequent urination, and weight loss. Medications such as metformin hydrochloride tablets, gliclazide modified-release tablets, or acarbose tablets may be used as directed by a physician.

In daily life, maintain skin cleanliness but avoid over-washing, which could compromise the skin’s natural protective barrier. Choose loose, soft, breathable clothing to minimize friction and irritation on the abdominal skin.
