It’s not always obvious that small, everyday signs could point to health issues. Take a scalloped tongue, for example — it might mean you’re eating too much salty food, or that your tongue is swelling and pressing against your teeth because it’s bigger than your jaw. Viral Strange has put together 10 everyday symptoms that could be linked to underlying health problems.

1. Dark Circles
Dark under-eye circles are usually linked to poor sleep or an unhealthy lifestyle.

2. Yellow Skin

Yellowish skin or the whites of your eyes could signal liver problems. It’s best to see a doctor quickly to avoid serious complications.

3. Finger Pain or Swelling
Thick or swollen fingers may be related to lung, kidney issues, or even breast cancer. If you notice this, seek medical advice immediately.

4. Unusual Hair Growth in Women
Hair growing in areas like the chin or above the lips may be a sign of PCOS (polycystic ovary syndrome), which stems from hormonal imbalance.

5. Persistent Pimple
If a pimple doesn’t go away after a few weeks, it could be a sign of basal cell carcinoma. Don’t ignore it — get it checked.

6. Thinning Eyebrows
Losing eyebrow hair can be an early symptom of hypothyroidism. It might be time for a thyroid check.

7. Acne Around the Jawline

Breakouts along the jawline or chin often point to hormonal imbalances.

8. Darkened or Thickened Skin
Skin that becomes darker or thicker could signal insulin resistance, a condition that might lead to type 2 diabetes.

9. Dark Lines on Nails
Black vertical lines on your nails may be harmless or due to injury, but they can also indicate melanoma.

10. Scalloped Tongue

A scalloped tongue means it’s swollen and pressing against your teeth. This can be caused by frequent consumption of salty foods, among other things.
