Moon On Nails, We are often delusional of our internal health. Conditions like heart attacks, blood pressures occur out of nowhere and can be fatal if not taken care of correctly and at the right time. They are best taken care of beforehand. Thankfully, our body does its best to alert us of the symptoms and we just have to notice them on time. One such alert can be the moons in our fingernails. The light semi circular part you see at the bottom of the nails are known as the moons of the nails, or lunula. It is a part of the nail matrix which consists of nerves, lymph and blood vessels. A change in their texture or shape can be an alert of dangerous conditions and just by noticing them, you can take proper measures to live better and healthier! Curious? Here are the facts you had been oblivious to! Lunula looks different in one finger (moon on nails) The Small finger The lunula on the small fingernail is usually not visible and if visible, not very prominent. The small finger is linked to the kidneys, the small intestines and the heart. If the lunula looks bigger or more prominent than before, it may be due to high blood pressure. The Ring Finger The Ring finger has connections to the reproductive and lymphatic systems. It is not usually visible, but if you can see yours, it may indicate problems with the digestive system. The Index Finger The Lunula on the index finger signifies a lot of things. It can show a significant decrease in size if there are problems related to the intestines, pancreas or diseases related to the ear, nose and tongue. The Thumb The Lunula on your thumb indicates the working of the Lungs and Spleen. While a visible Lunula on the thumb is common and not a matter of concern, it should not be too big( taking more than 25% of the nail). It has been observed that, in cases of arterial hypertension, it can get significantly smaller or larger in smokers. Some Special Conditions When the Lunula is extremely Big A lunula can be called big when it covers about one third or more of the whole nail. A big lunula can be an alarming indication of cardiovascular problems, low blood pressures or heartbeat deterioration. Large lunulae is usually common among people who are into a lot of exercises or sports, especially athletes. If your lunula looks larger but you are not into much physical activity, it maybe due to too much stress. When the Lunula is Small If your lunula is very small, not prominent or barely visible, it may indicate problems with the blood pressures or circulatory disorders. Small lunula may also imply weak immune system, poor metabolism or an acute deficiency of irons and vitamins. Separated Lunulae If the lunulae appears separated from the rest of nail plate, mostly by transverse lines, may indicate blood sugar or diabetes. No lunulae Unlike what you are probably guessing, this condition is pretty normal! The lunula isn’t visible in many people due to different nail structure. It usually appears with age so it’s normal for children to not have it. However, if you had lunulae and they’ve disappeared suddenly, it can be an indication of circulatory disorders, trauma, anaemia, vitamin deficiency or depression. Change in the colour of the lunula Blue lunulae can be the sign of Wilson’s Disease. Blue-grey lunulae may signify Silver Poisoning. Grey Lunulae indicates problems with the digestive system. Purple Lunulae signify poor blood circulation and the lack of oxygen in tissues. Pale Blue Lunulae might be an indication of Diabetes. Brown Lunulae can indicate Fluoride Poisoning, Renal Failure or any other kind of Renal Disease. Black Lunulae may also be an indication of Fluoride Poisoning. Red Lunulae may symbolise heart failure. Yellow Lunulae may indicate excessive Tetracycline Therapy. Black Lunulae, the most dangerous of all, is a sign of heavy metal poisoning. If your whole nail turns White, it is a symptom of Terry’s Nails or Renal Disease. The whole nail turning Yellow is a symptom of Yellow Nail Syndrome. Bottom Line While a change in Lunulae is usually not a matter of concern, it does at times indicate serious conditions and if you have noticed any of the conditions mentioned above, we suggest you to get checked by your physician for the related diseases. Prevention is always better than cure, right?
