The skin is connected to several body systems, including the immune, endocrine, and circulatory systems. Changes in skin health can occur alongside changes in other areas of the body, so dermatology is relevant to more than appearance. Some skin conditions also have connections to internal health factors, such as hormonal activity and immune function. Here is some information about the connection between dermatology and overall health:
Skin Cancer Prevention
Regular skin checks help you identify changes that may warrant further evaluation by a dermatologist. A dermatologist looks for changes in moles and spots using the ABCDE guide:
- Asymmetry: one half doesn’t match the other
- Border: edges are irregular or blurred
- Color: shades vary within one spot
- Diameter: the spot is larger than 6 millimeters
- Evolving: size, shape, or color changes over time
During a full-body skin exam, a dermatologist may use a dermatoscope. This handheld magnifying tool shows patterns beneath the skin’s surface that are not visible to the naked eye. Risk for skin cancer varies; fair skin that burns easily, a history of blistering sunburns, and a family history of melanoma often increase risk.Â
If a spot looks suspicious, your dermatologist may remove a small sample for a biopsy. A lab examines the tissue under a microscope, and results show whether cancerous or abnormal cells are present. For daily protection, use a broad-spectrum sunscreen with SPF 30 or higher and wear protective clothing when UV levels peak.
Rash Evaluation
A rash is a change in the skin’s color, texture, or appearance. Its causes range from a reaction to laundry detergent to an autoimmune disease, and some triggers are difficult to identify. Dermatologists usually ask about when the rash appeared and whether it itches. They also review your medications and any new soaps or lotions.Â
Location and shape offer clues. A ring-shaped rash may point to a fungal infection, while a butterfly-shaped rash across the cheeks and nose is sometimes associated with lupus. Psoriasis, which causes thick, scaly patches, is linked to a higher risk of arthritis. When the cause is unclear, your dermatologist may order a patch test, blood work, or a skin biopsy.
Infection Control
Bacteria, viruses, fungi, and parasites all infect the skin. Common infections include cellulitis and athlete’s foot. Untreated cellulitis may spread to the bloodstream, so redness that expands, feels warm, or comes with a fever needs prompt medical attention. Recurring skin infections are sometimes a sign of an underlying condition, such as diabetes or a weakened immune system. A dermatology clinic identifies the cause through a culture or skin scraping and prescribes treatment that matches the organism. At home, wash cuts with soap and water and keep them covered.
Visit a Dermatology Clinic
Skin changes can be minor, but sometimes they indicate a larger health issue. A dermatologist examines your skin, hair, and nails and explains what the findings mean for you. If you see a new or changing spot, a rash that won’t clear, or signs of infection, contact a dermatology clinic. Schedule an appointment today for a skin exam or to discuss your concerns with a provider.
