What illness might全身 itching after eating sweets be a precursor to?

Itching all over the body after eating sweets may be an early sign of conditions such as urticaria, sugar allergy, or diabetes, and active treatment based on the specific condition is necessary. Detailed analysis is as follows:

1. Urticaria

Urticaria is a common skin disorder characterized by red, swollen, itchy patches or papules on the skin. Itching all over the body after consuming sweets may result from urticaria triggered by an allergic reaction to certain food components. Medications such as loratadine can be used under medical guidance.

2. Sugar Allergy

If a person is allergic to sugar, it may cause physical discomfort and even lead to symptoms such as skin itching. It is important to avoid sugary foods. If necessary, antihistamines such as chlorpheniramine can be taken under a doctor’s supervision.

3. Diabetes

Individuals with diabetes often experience symptoms such as excessive thirst, frequent urination, and weight loss. Over time, they may develop peripheral neuropathy. After consuming sweets, blood glucose levels rise rapidly, which may trigger neurological symptoms and affect peripheral nerves, leading to skin itching. Medications such as metformin sustained-release tablets or rosiglitazone tablets may be prescribed under medical supervision.

In addition, this symptom could also be an early indication of liver disease, kidney disease, or other conditions. Further examination and diagnosis are required to identify the underlying cause before appropriate treatment can be initiated.
