Skin rash and pruritus are a relatively common condition, which can occur for any age. These are depending on the cause and the health of the person.
Causes of Skin Rash And Itching
We often think that the skin is a perfect “shield” – protecting our bodies from external agents. However, our skin also contains many specialized cells of the immune system.
These cells protect the skin and the body against viruses, bacteria, and other threats. Whenever these cells detect something suspicious, they will start reacting to the condition leading to skin rash and possibly itching.
Here are some of the skin rash causes that can lead to skin itching.
Allergy, an abnormal reaction of immune system to specific foreign substances, known as allergens. Early exposure to allergens may not produce any abnormalities. However, over time, the body’s immune system begins to form antibodies to these allergens, so the symptoms of exposure to these substances gradually change, becoming more serious.
Symptoms of exposure to allergens include rashes and itching, sneezing, difficulty breathing, shock or even death. Many things can cause allergic reactions: pollen, pet hair, perfume, food, cosmetics, medicine, etc.
Too hot or too cold can cause skin rash and itching, especially for people with sensitive skin.
- Heat rash (thermal rash) is a red or pink skin rash on areas of the body, which occurs when the weather is too hot, high humidity. Blocked sweat leads to discomfort and itching. Hypothyroidism is common in infants or adults living in hot, humid climates.
- Urticaria is an inflammatory reaction of the skin. It occurs when the person exposed to cold temperatures. The body will be rash (weather allergy), this can also be genetic, due to virus infection or some related diseases. Other symptoms may appear like fever and joint pain. Red rashes will be exposed when exposed to cold air and may last several hours to several days. It can happen frequently.
Eczema is considered to be a disease caused by an overactive immune system. Typical symptoms are dryness, itchy skin, skin rash. These rashes may contain fluid inside. It is usually common during life, common in infants and children. People who suffer from this condition are more likely to have allergic rhinitis and asthma.
It is a skin rash that affects mainly young people. The rash is usually red, scaly, small pink spots that can spread to the chest and abdomen, arms and legs, causing itching. It usually lasts 6-8 weeks but can last for three weeks or lasts for more than two months.
5. Steven Johnson Syndrome
Steven Johnson syndrome is a potentially life-threatening skin lesion in the skin and mucous membranes, often with sudden onset of multiple skin rashes. There are many skin abrasions.
Accompany it with diffuse mucosal lesions, such as ulcerative colitis in the mouth and around the mouth, conjunctivitis, conjunctival bleeding, corneal ulceration.
This disorder is usually an allergic reaction of the body to certain medications or infection. The most common drugs that cause this syndrome are sulfa, tetracycline, amoxicillin, ampicillin, antiepileptic drugs, NSAIDs (ibuprofen, naproxen) and allopurinol.
6. Fungal Infections
Mushrooms grow like yeast or mold. Fungi often cause illness in people through the inhalation of spores into the lungs, or through contact on the skin.
Fungi (yeasts) that cause vaginal infections can develop after taking antibiotics. Skin fungal infections can found in areas: on the scalp, in men’s beard, in the groin, between the toes. Smooth skin is caused by mold, which occurs at any age and is common in children. Smooth skin thrives in a humid environment and spreads quickly through contact with the person.
7. Parasitic Infections
Some types of parasites reside on the skin, hair, body, genitals of humans or animals. They live by sucking host blood, causing discomfort, skin rash and itching. Indirect causes are usually due to poor hygiene.
Folliculitis occurs when infected hair follicles, usually caused by Staphylococcus or other bacteria. It causes skin rash and itching in certain areas.
Another variant of hair follicular inflammation is called hot tub folliculitis (due to contact with bacteria in hot tubs) and itching nails (skin irritation when shaving).
Severe infection can cause hair loss and scarring on the skin.
9. Burning Insects
Insects are present everywhere when it injected or burned into the skin, which can contaminate with bacteria, viruses or toxins from insects. As a result, it causes an immune reaction of the skin, which causes the skin to become red and itchy. Common insects that cause this condition include fleas, lice, scabies, etc.
10. Primary Bile Duct Inflammation
Bile ducts drain the bile from the liver or from the gallbladder to the gastrointestinal tract. Primary biliary atresia is a disease characterized by inflammation and scarring in the bile ducts, narrowing the bile ducts, thereby blocking the flow of bile.
Cirrhosis and liver failure can occur at the same time. The disease can progress to bile duct cancer in about 15% of patients. This disorder usually associated with inflammatory bowel disease.
11. Hepatic Congestion in Pregnancy
It is a phenomenon of cholestasis in the liver during pregnancy, as the flow of the gallbladder from the gallbladder to the small intestine is slowed or blocked. This disorder usually occurs in the last three months of pregnancy. It does not cause harm to mother but can harm the fetus.
Factors that increase the risk of this disorder include the family history of a person with this disorder, multiple pregnancies (twins, triplets, etc.) and previous liver damage in the mother.
12. Mast Cell Disease
Mastocytosis or Mast cell disease caused by abnormal growth of mast cells (inflammatory cells made from bone marrow) that cause histamine.
Histamine causes swelling, itching, and redness and is one of the causes of allergic reactions. It can happen at any age and is common in children. The disease usually disappears in puberty.
13. The Larvae Move Outside the Skin
It is a skin rash caused by a parasitic infection (roundworms). Risk factors include sunbathing or barefoot in the tropics, hobbies or occupations that require exposure to sandy soils. It can cause skin rash and itchy redness.
