What diseases cause itching all over?

Itching All Over The Body 

Itching diseases are one of the most common problems in human bodies. You might be having itching when you are in contact with different kinds of allergies.

Disease symptoms can be very confusing. Understanding symptoms should not be difficult, especially if you know what to look for. The first step to identifying what disease is causing the itching sensation is understanding that itching is one of the ways that the body responds to an irritant.

The next step is to understand what diseases cause itching all over. Healthline says that other diseases that can cause itching all over are: Pneumonia, hives, side effects of medications (such as blood pressure pills), food allergies (such as peanuts), poison ivy, sunburn, chiggers, scabies, alopecia areata, contact dermatitis, eczema, psoriasis, shingles, vitiligo.

Itching skin is a common complaint. Fortunately, there are a number of conditions that can cause this symptom, some of which may not be serious.

Unbearable Itching

As the summer season sets in, people start to notice rashes appearing on their skin. Inflammation of the skin is more common in warmer months of the year because the increase in sweating causes the skin to lose moisture and become dry.

There are several reasons for whole body itching, and depending on the cause, the itching may occur in one area of the body, or many areas.

The following are a few common causes of whole body itching:

1. Allergies: Allergies to things such as pollen, pet dander, poison oak, grass, etc. can cause an itchy rash anywhere on the body. Food allergies (e.g., milk and eggs) can be another cause.

2. Contact dermatitis: Dermatitis causes the skin to itch when it becomes inflamed or irritated. The most common cause of dermatitis is contact dermatitis, which is caused by contact with an allergen. 

3. Dry skin: When the skin does not produce enough oil or moisture, it can become dry and itchy. This type of itchy rash is generally found on the elbows and knees. 

4. Stress: When you are under stress, your body can release chemicals that trigger itching. Stress-related rashes may appear, disappear, and then return again at stressful times in your life.

5. Scabies: We’ve also had a few queries regarding ailments like scabies and eczema; we definitely had to look into those as well! Scabies is a skin infestation of the mite Sarcoptes scabiei. Itching may occur after a few days of exposure to the infected person.

6. Extensive allergic dermatitis: This type of dermatitis causes intense itching and is caused by exposure to certain plants, such as poison ivy. This causes the body to release inflammatory chemicals that can make the skin feel itchy and irritated.

7. Dermatitis herpetiformis: This disease causes intense itching and is caused by gluten intolerance in people who have the gene for celiac disease.

8. Dermatitis caused by bacterial infections: Infection with bacteria in the genus Streptococcus (often group A streptococcus) does it. The infected person has a non-raised red spot on the skin with a yellow or orange colour. Their skin is usually very hot and dry and they have fever, nausea, headache and vomiting.

9. Fungal infections: Ringworm is a fungus that can cause an itchy rash in both children and adults. Ringworm is highly contagious and it spreads easily to other parts of your body or other people. Tinea corporis is another fungal infection that causes itching all over the body.

10. Bugs and insect bites: When you get bitten by a mosquito or spider, you know it. Bites from bedbugs and mites can be harder to diagnose because they look like rashes. Following an insect bite or sting, itching and redness of the skin are common and may last for up to 10 days. 

Home Remedies to Soothe Itching
