Why do I feel itchy all over my body? Why do I feel itchy all over my body?

If a person suddenly experiences itching all over the body, it must not be ignored, because itching all over the body is not only caused by mosquito bites or bacterial infections, but may also be caused by the accumulation of toxins in the human body. If you want to treat itching all over your body, you should first find out the cause and then take appropriate measures. The following article will introduce to patients some specific reasons that cause itching all over the body.

1. Itching all over the body may be caused by toxin accumulation in the body

If our body's immunity becomes low, the toxins in the blood will accumulate under the skin, making it impossible for the skin to breathe normally, and the condition will become more serious over time.

2. Itching all over the body may be caused by taking baths too frequently

In the summer, we sweat every day, so we have to take a shower every day. Some people even take a shower several times a day. The oil film on the skin surface and the lipids in the stratum corneum will be excessively removed, and the skin's barrier function will be weakened, causing the skin to become drier and itching.

3. Itching all over the body may be a simple skin problem

There are two situations in which you feel itchy due to skin problems: one is that there is no primary skin damage, which is mostly caused by lack of moisture in the skin. Just like in winter, many people feel dry, itchy and peeling skin. The other is that the skin itself is "sick". Skin diseases such as dermatitis, eczema, and psoriasis are mostly accompanied by itching.

4. Itching all over the body may be caused by skin degeneration in middle-aged and elderly people

The skin of middle-aged and elderly people shrinks and becomes thinner, the water content decreases, and the secretion of sebaceous glands and sweat glands decreases, causing the skin to lose its lubricating and protective function and appear dry. In cold seasons, the dry climate makes the skin rough and even causes peeling of the epidermis, making the nerve endings in the skin more easily irritated and itchy. This is the reason why many elderly people suffer from itching.

5. Itching all over the body may be caused by allergies

Clinically, one-third of patients who visit the allergy department have symptoms of itchy skin. Allergies to food, pollen, dust mites, and contact with certain chemicals may cause allergies, making the skin feel itchy. This type of itching usually gets better after you stop coming into contact with the allergen.

6. Itching all over the body may be caused by emotional tension

Negative emotions such as depression, tension, and irritability may cause local or systemic skin itching.

7. Itching all over the body may be a sign of liver and gallbladder disease

Studies have shown that approximately 40%-60% of patients with hepatobiliary diseases will experience skin itching when they have liver discomfort, abnormal liver function, or jaundice.

8. Itching all over the body may be caused by diabetes

The incidence of skin itching in diabetic patients is as high as 15%-35%. About 10% of early patients will experience systemic or local skin itching, which is relatively stubborn, with the most severe symptoms in the vulva or anus.

9. Itching all over the body may be caused by chronic renal insufficiency

Patients with chronic nephritis, especially those in the late stage (uremia stage), cannot be excreted from the body due to the presence of metabolites such as urea and toxins in the blood. They are retained in the body in large quantities and are excreted along with the sweat when sweating, causing unbearable itching all over the body.

10. Itching all over the body may be caused by abnormal thyroid function

Whether it is hyperthyroidism or hypothyroidism, itchy skin may occur, but the itching caused by hyperthyroidism usually develops slowly, the skin is often dry, and it will worsen in winter.

11. Itching all over the body may be a malignant tumor

Some tumors may be accompanied by itchy skin, such as cancer of the lymphatic system, stomach, intestine, liver, ovary and prostate. This kind of itching caused by tumors is mostly stubborn. If you have itching on your body for a long time without any reason, you need to pay attention to it.
