3. Clubbed Nails
Nail clubbing, or digital clubbing, is a condition that gradually occurs over a number of years. The tips of the fingers progressively become enlarged. As the fingertips change in shape, the fingernails adapt and begin to curve over the fingertips. This condition may occur due to low levels of oxygen in the blood, leading to decreased oxygen supply to the fingertips. Therefore, clubbed nails may indicate lung disease. Clubbed nails may also be a sign of diseases such as inflammatory bowel disease, liver disease, AIDS, and heart disease. Treatment for nail clubbing will depend on the underlying condition.
2. Pitted Nails
Nail pitting refers to tiny dents or craters in the surface of the nail plate. This condition can be a sign of autoimmune disorders such as psoriasis or alopecia areata. Alopecia areata is a skin condition in which your immune system attacks healthy hair follicles, resulting in hair loss. Reiter’s syndrome is another condition that may cause pitted nails. Reiter’s syndrome is reactive arthritis, a rare disorder in which infections in parts of your body such as the gastrointestinal or urinary tracts trigger arthritis in your joints. In addition to joint pain, this condition can cause inflammation of muscles and tendons, swollen fingers and toes, and skin problems.
1. Spoon Nails
The term spoon nails refers to nails in which the edges of the nails have lifted up from the nail bed. This results in fingernails that look like little cups or scoops. Spoon nails, or koilonychia, may be indicators of iron deficiency, anemia, heart disease, or hypothyroidism. Iron is necessary for energy, growth, immunity, red blood cell formation, and wound healing. Beans, dark green vegetables, meats, and poultry are good sources of this essential nutrient. Whole grains and fortified breads and cereals also contain the iron your body needs.
