Feeling good is within the power of your hands.
HEALTH When a doctor looks at your hands during a routine exam, he may see more than what you are embarrassed to admit. Those questions about how often and and how long you exercise can seem intrusive to patients who are not athletic.
Healthy fingernails should be smooth and glossy with a white crescent called the lunula occupying one fifth the surface near the cuticle. It is normal to have 8 to 10 lunula (two genrally absent from pinky fingers). The lunula is not just pigment. Even when the nail is totality removed, the lunula remains in place and is similar in appearance to another smaller fingernail embedded in the nail bed. It contains stem cells and nail plate matrix which helps the growth of the nail.
According to Eastern medicine, a more energetic person has a correspondingly whiter lunulae. Lower energy, poorer health, poor blood circulation, depleted immunity, and a possible digestion issue is indicated by less lunula; when the lunula only appears on the thumbs, physical energy is insufficient and the disease is imminent. People with absent fingernail moons are not necessarily ill but they always have serious diseases when they feel sick. Conversely, some Western doctors may view lunula absence as simply atypical; others express more concern.
A red lunula is common among patients with chronic obstructive pulmonary disease (COPD). In patients with Wilson’s disease (hepatolenticular degeneration), the area takes on a blue coloration, a phenomenon called azure lunula. Heart failure can turn the lunula red, and tetracycline therapy can turn it yellow. Silver poisoning will turn the nail itself a blue-gray color. Excessive fluoride ingestion can turn nails brown or black. Chronic renal failure affects almost all the systems of the body, including the skin and appendages. The three nail disorders most commonly found in patients with chronic renal failure are half-and-half nails, absent lunula and splinter hemorrhages.
