Check them in color too, together with the skin surrounding it and the skin underneath. They can all tell you different things. If you want to know more, keep reading.
Fingernails Warning Signs
1. Clubbed Nails
Clubbed nails are those which are puffed around the fingers. Also, the skin around the nail might seem swollen. These can indicate:
- Liver Disease
- Inflammatory Bowel Disease
- Lung disease, especially if you already have trouble breathing
2. Dry, Brittle Nails
Usually, brittle nails are connected with bacterial infections and hormone imbalance. Also:
- Thyroid disease can lead to brittle and dry fingernails.
- Fungus too makes nails dry or even crumbly, which affects 12% of all Americans.
Healthy nails should have smooth surfaces with invisible lines. Ridge lines can be a warning of conditions like:
- Iron Deficiency
- Inflammatory Arthritis
Instead of buffing away the ridges, look for the underlying cause.
4. Pitted Nails
If you have small dips in the nails it might mean that you have caused them by banging them or you have a health problem like:
- Zinc deficiency
- Alopecia areata, an autoimmune disorder that causes hair loss
- Connective tissue disorder
5. Concave (Spoon Nails)
Nails like these curve up and form a dip. They can also indicate a lot of issues, like:
- Heart Disease
- Hemachromatosis, a liver disorder where your body absorbs too much iron

6. Split Nails
These types of nails usually flake away in later. However, a lot of people blame this on the nail polish, when it actually might be:
- Caused by chronic malnutrition
- If they are split and have a pitted nail bed (base) it can indicate psoriasis, which starts in nails 10% of the time.
- They can stem from folic acid, vitamin C and protein deficiencies.
7. Thick Nails
Having thick nails is not normal. Nails have to be strong. If not, they can indicate:
- Lung disease
- Circulation problems
- Fungal infection

8. Discolored Nails
