Common Skin Disorders – Symptoms, Causes and Treatment

Skin disorders are ailments that affect your skin, and they may cause rashes, inflammation, itchiness, or other skin changes. Genetics can cause some skin diseases, while lifestyle factors may cause others. Some skin disorders are temporary and minor, while others can be permanent and life-threatening. Medication is usually necessary to treat most skin disorders; however, some can be treated with creams or ointments.

3. Shingles (Herpes Zoster)

After a case of chickenpox, the virus that causes it (varicella-zoster) may lie dormant in your nervous system for years. If your immune system is weakened, the virus may reactivate, causing shingles. Shingles typically appear as a red rash that wraps around your torso or elsewhere on your body.

Hives are the familiar welts that sometimes appear on a person's skin. Those welts may be caused by food allergies, bug bites or stings, or medicines. If hives are accompanied by swelling of the throat or facial areas, if they persist for more than 4 hours, or if they interfere with breathing, then seek medical attention.

Symptoms of Hives (Urticaria) –

Formation of skin coloured welts or red batches
Welts with varied shapes and sizes that appear and fade

5. Rosacea

Rosacea is a common skin disorder that causes pimples, dilated blood vessels and rosy red patches. It often occurs in women aged 30 or above, but men are also affected. Problems with the vein, immune system problems and environmental factors can cause the disorder.

6. Athlete's Foot (Tinea Pedis)

An athlete's foot is a fungal skin infection. It causes white or yellowish scaling between your toes and itching, redness, and cracked skin on the feet and in between your toes. It is caused by the Fungi called dermatophytes, commonly found in moist and warm areas like locker rooms, pool decks, and shower towels.

Cracked and scaly skin between toes and bottom of foot
Sensation of itching
Greyish, reddish or purplish inflamed skin

7. Psoriasis

Psoriasis is an autoimmune disease and a chronic, or lifelong, skin disorder. It can cause patches of skin to become scaly and red, often accompanied by an itchy, burning sensation. These patches can come and go over several weeks.

Symptoms of Psoriasis –

Red patches with silvery and thick scales cover the skin
Tiny scaling spots
Cracked and dry skin with itchiness
Sensation of soreness and burning
Ridged, thickened or pitted nails
Stiff and swollen joints

8. Actinic Keratosis

Actinic keratosis (AK) usually forms in areas exposed to the sun for long periods. AK develops when keratinocytes (skin cells) grow abnormally and create scaly, discoloured spots.

Flat patch or bump on the top skin layer
Varied colours including brown, pink or red
Sensation of burning, crusting, bleeding or itching
Fresh bumps or patches on parts exposed to sun

9. Vitiligo

Vitiligo is a skin disorder in which the cells responsible for skin colour, called melanocytes, stop functioning. When these cells lose the ability to produce melanin or skin pigment, it causes the skin to lose its colour and gradually turn white.

Symptoms Vitiligo –

Patchy skin colour loss starts from the hands and spreads to other body parts
Premature whitening of scalp, eyebrows, beard and eyelash hair
Colour loss in the mucous membrane

10. Skin Cancer

Skin cancer occurs when skin cells divide and multiply uncontrollably, forming a mass of tissue called a tumour. When this happens, the cells may become abnormal, leading to the development of cancer. Some types of cancerous tumours are benign, which may not be harmful. Other types have the potential to spread to other parts of the body, and if not treated early, they can be fatal.

Symptoms of Skin Cancer –

Waxy and pearly bump
Brown, flat, flesh-coloured scar-like lesion
Scabbing and bleeding sore that heals but returns
Red coloured firm nodule
Flat lesion with a crusted and scaly surface
Dark speckles with a big brownish spot
Mole that bleeds and changes feel, colour and size
