Our skin is our largest organ and it can reveal a lot about our health. There are many serious illnesses that can manifest themselves on our skin, ranging from visible rashes and lesions to more subtle changes in skin texture and color.
These changes can be a sign of an underlying health condition and should not be ignored. Here are some of the most common skin manifestations of serious illnesses.
1. Psoriasis
Psoriasis is a chronic autoimmune disease that affects the skin. It causes red, scaly patches that can be itchy and painful. These patches may appear anywhere on the body, but are most commonly found on the scalp, elbows, knees, and lower back.
The exact cause of psoriasis is unknown, but it is believed to be related to an overactive immune system.
2. Lupus
Lupus is an autoimmune disease that can affect many parts of the body, including the skin. It can cause a butterfly-shaped rash on the face, as well as other rashes and lesions on other parts of the body.
Lupus can also cause joint pain, fatigue, and other symptoms.
3. Eczema
Eczema is a common skin condition that causes dry, itchy skin and a red rash. It is often caused by an allergic reaction to something in the environment, such as dust mites or certain foods.
Eczema can be treated with topical creams and ointments, but it can also be a sign of an underlying health condition, such as a food allergy or autoimmune disease.
4. Skin Cancer
Skin cancer is the most common type of cancer in the United States. It is caused by damage to the DNA in skin cells, often from exposure to ultraviolet (UV) radiation from the sun.
Skin cancer can appear as a mole or other growth that changes in size, shape, or color, or as a sore that does not heal. It is important to get any suspicious spots on the skin checked by a doctor.
