Small red itchy spots on the body
Small red itchy spots on the body may be caused by physiological factors, but pathological factors such as eczema or urticaria cannot be ruled out. The specific analysis is as follows:
I. Physiological Factors
After insect bites, extensive bacterial invasion of the body may cause small red spots on the skin. Poor dietary habits, long-term consumption of spicy and stimulating foods, and frequent熬夜 (staying up late) can stimulate hormone secretion in the body, leading to symptoms such as redness, swelling, and itching of the small spots. Adjusting lifestyle habits can help regulate these conditions—maintain a light diet, avoid spicy food, drink plenty of water, and promote the elimination of toxins from the body.
II. Pathological Factors
1. Eczema
If the skin is exposed to external irritants, hair follicles may sustain some damage. Under inflammatory effects, this can trigger eczema. If not treated promptly, localized small red spots may develop on the skin, accompanied by pruritus (itching) and mild discomfort. Under a doctor's guidance, topical medications such as tacrolimus ointment or mupirocin ointment can be applied to reduce inflammation and relieve itching.
2. Urticaria
Irregular dilation of blood vessels can lead to edema of the skin and mucous membranes. When symptoms are prominent, numerous red spots may emerge from the skin surface, causing intense itching. Scratching may further result in severe pain. Under medical supervision, antipruritic drugs such as fexofenadine hydrochloride capsules or loratadine dispersible tablets can be used to alleviate skin itching and effectively reduce stinging pain.
In addition, allergic dermatitis could also be a possible cause. If small red spots appear on the body, do not arbitrarily use medications without consultation. It is recommended to seek medical attention at a hospital for targeted treatment under professional medical guidance.
