Signs you should know if you have this thing called…

A yellow tint to the skin and the whites of the eyes is a hallmark sign of jaundice, which usually points to liver dysfunction. This discoloration results from an accumulation of bilirubin, a yellow pigment that the liver typically processes and eliminates.

Possible Causes:

  • Chronic liver diseases (e.g., hepatitis, cirrhosis)

  • Gallstones or biliary duct obstruction

  • Side effects of certain medications or toxins

  • Hemolytic anemia (excessive breakdown of red blood cells)

Note: Jaundice can also occur in newborns due to immature liver function but should always be evaluated by a healthcare provider if it appears in adults.

2. Dark Patches on the Neck or Armpits

Darkened, thickened patches of skin—especially in body folds like the neck, armpits, or groin—may signal insulin resistance, which often precedes type 2 diabetes. This condition is called acanthosis nigricans and is sometimes accompanied by a velvety texture.

Associated Conditions:

  • Obesity

  • Polycystic ovary syndrome (PCOS)

  • Hormonal disorders

  • Certain cancers (in rare cases)

Tip: If these patches appear suddenly or spread rapidly, it’s important to consult a doctor promptly.

3. Persistent Redness or Rashes

Continuous redness, especially on the face, with visible blood vessels or bumps, may indicate rosacea, a chronic inflammatory skin condition. However, if rashes appear elsewhere on the body, they might point to:

  • Allergic reactions or contact dermatitis

  • Autoimmune conditions such as lupus or dermatomyositis

  • Chronic infections or inflammatory diseases

Some rashes are also photosensitive and worsen with sun exposure—another clue that something systemic may be occurring.

4. Brittle or Mottled Nails

Though not skin itself, nails are part of the integumentary system and can reveal internal imbalances. Changes in nail color, texture, or strength—such as brittle nails, horizontal lines, or unusual ridges—might reflect:

  • Nutritional deficiencies (iron, biotin, protein)

  • Thyroid disorders (hypothyroidism or hyperthyroidism)

  • Heart or lung disease (e.g., clubbing of fingers)

Dark lines or streaks under the nail can sometimes indicate melanoma and should be checked without delay.

5. Extreme Dryness and Flaking

Chronically dry, rough, or scaly skin that doesn’t improve with moisturizers may be more than a cosmetic issue. It could signal:

  • Hypothyroidism

  • Psoriasis or eczema

  • Dehydration or malnutrition

  • Chronic kidney disease

In some cases, dry skin may become cracked and painful, increasing the risk of infections if the skin barrier is compromised.

6. Unexplained Bruising

If you notice frequent or unexplained bruises, especially in areas not prone to injury, it could suggest a problem with blood clotting or capillary fragility.

Potential Causes Include:

  • Vitamin K or C deficiency

  • Blood disorders like thrombocytopenia or leukemia

  • Side effects from medications such as blood thinners or steroids

  • Aging, which makes blood vessels more fragile

Persistent bruising, especially when paired with fatigue or bleeding gums, should be evaluated promptly.

When to See a Doctor?

Don’t ignore skin changes that:

  • Appear suddenly or worsen over time

  • Are accompanied by systemic symptoms like fatigue, fever, weight loss, or chronic pain

  • Are painful, itchy, or spreading

A dermatologist is a good first step in evaluating skin-related symptoms. However, since skin issues can often stem from deeper causes, other specialists like endocrinologists, gastroenterologists, rheumatologists, or hematologists may also be involved in diagnosis and care.
