1. Yellowish Skin (Jaundice)
Yellow discoloration of the skin and eyes is often related to liver problems, such as hepatitis or cirrhosis. It is due to an excess of bilirubin in the blood, which the liver cannot process properly.
Possible Causes
- Chronic liver disease
- Biliary obstruction
- Adverse reactions to medications
2. Dark spots on the neck or armpits
The presence of thickened, brownish areas in skin folds may indicate insulin resistance, a common precursor to type 2 diabetes.
This condition is known as acanthosis nigricans.
3. Persistent redness or rashes
Chronic facial redness, with visible vessels or inflammatory flare-ups, may be a sign of rosacea. If lesions appear on other parts of the body, they may be associated with allergic reactions, infections, lupus, or even autoimmune diseases.
4. Brittle or mottled nails
Although not skin itself, nails are part of the integumentary system. Brittle nails, with dark lines or changes in shape, may indicate nutritional deficiencies, heart disease, or thyroid problems.
5. Extreme Dryness and Flaking
Dry skin that doesn’t improve with moisturizing may be linked to conditions such as hypothyroidism, psoriasis, or atopic dermatitis. It could also be a sign of chronic dehydration or nutrient malabsorption.
6. Unexplained Bruising
If the skin bruises easily and without obvious bruises, there may be a clotting problem, vitamin K deficiency, or blood disorders such as thrombocytopenia.
When to See a Doctor?
These signs should not be ignored, especially if they appear suddenly, worsen over time, or are accompanied by other general symptoms such as fatigue, fever, weight loss, or pain.
A dermatologist may be the first step in an evaluation, but in many cases, an interdisciplinary approach will be required, including endocrinologists, rheumatologists, or gastroenterologists, depending on the cause.
