There are 4 fingernail conditions that show poor health. The body informs us in multiple ways which systems are not functioning well. Many indications of malfunction are as subtle as the condition of the fingernails. Our nails can not only signal that something is wrong, they also point to where.

Physical diagnostic signs found in the nails were studied by medical researchers during the 1800s when the practice of medicine had a different focus.  Lucky for us, these signs still apply.  The purpose of these signs is for us to learn to read them. More importantly, we can address some of our problems using natural tools. Here are 4 things about fingernails that show your state of health:

The 4 Fingernails Conditions That Show Poor Health

Hands interlocking in the sandTake a moment and notice the ridging, shape, color, and texture of your fingernails.  These visual cues indicate which system in your body is on the fritz.  Let’s take a closer look at what factors can mean for your health and what solutions are available to help.


Ridging of the nail normally runs vertically, up and down the nail.  Any ridging or depressions that occur horizontally (not through injury) is considered a metabolic problem.


The normal shape of a nail slightly curved from bottom to top.  An abnormally shaped or visibly humped nail is associated with many chronic diseases, such as COPD, asthma, ascites (swollen abdomen), and angioedema.

Half-moons are normal for each nail.  Nails without half-moons indicate that an organ system is diminished.


The color on any nail bed is generally pink; however, nailbed color can vary from blue to white.  Blue can signify vascular problems, even cardiovascular.  The darker the blue, the more concerned you should be unless you have injured the nail.  White nail beds are on the opposite end of the spectrum.  White generally indicates poor circulation or an anemia that is probably chronic.

Blackened nail beds (not due to injury) can be indicative of such morbid conditions as cancer and fungal conditions.

Yellow nail beds are usually associated with fungal overgrowth and a need to detox.

White spots on the nails generally indicate periods of stress, and more importantly, a need for minerals – especially calcium.


Peeling nails are a sign of nutritional deficiency, mainly minerals and vitamin C—which are instrumental in helping the body to rebuild and regenerate connective tissue.

Dry, brittle, thin nails are associated with hypothyroidism or adrenal dysfunction.

By the Finger – Nail

Other factors in the ridging, shape, color and texture of the individual nail can help point to potential health problems in specific organ systems.  All signs can indicate a number of things, but here are some of the most common experiences and conditions:



The thumbnail is related to the system of elimination.  There are two systems of elimination:  urinary—consisting the kidney, ureters, and bladder; and the colorectal system which has only the colon.

Abnormal ridging on the thumbnail indicates problems with metabolism.  Symptoms may include pain or discomfort in the lower abdomen.

 Blue on the thumbnail could be congestion of the blood or other symptoms involving the colon or urinary system. Other symptoms to look for are gas, bloating or a dull ache in the abdomen or lower pelvis.  Also be aware of frequent trips to the restroom.

White on the thumbnail is usually evidence of an unhealthy elimination system. Additional symptoms may be foul smelling stools or urine, recurring infections, or an unusual discharge.

Fore/Index Finger-Nail

The index fingernail represents the reproductive system, including the breasts, uterus, vagina, ovaries; prostate, gonads, and penis.

If you notice abnormal ridging on the index fingernail bed, keep an eye out for issues with generalized sexual dysfunction.

Blue on the index nailbed generally indicates congestive or poorly oxygenated blood.  You may also experience low sexual energy or drive, dull achiness in the pubic area.

A white or pale index nail bed could be a signpost of the low vitality of the reproductive organs. Symptoms could appear as discharge (in males and females), low sexual function, or low libido.

Middle Finger-Nail

The middle fingernail represents the digestive system, comprised mainly of 4 organs – the stomach, liver, gallbladder, and small intestines.

Abnormal ridging on the middle fingernail bed is associated with a metabolic problem in one or more of the digestive organs.  Watch out for excessive burping, heartburn, bloating, or pain in the digestive organs.

Blue on the middle fingernail bed could point to congested gall bladder, G.I.R.D (gastrointestinal reflux disease). If your nail bed is blue, you may also experience belching, flatulence, or general discomfort in the upper abdomen (when poked).

A white or pale middle fingernail generally specifies diminished blood supply to the digestive organs.  Symptoms of diminished blood supply include a poor appetite, smelly or oily stools, and a tendency to vomit.

Ring Finger-Nail

The condition of the ring finger nail bed represents the condition of the cardiovascular system, which consists of the lungs, heart, and sinuses.

Abnormal ridging is associated with problems in the respiratory system.  Symptoms of a malfunctioning cardiovascular system may include COPD, asthma, heart irregularities, severe and chronic sinusitis.

Blue nail beds signify problems of congestion in the cardiovascular system. There is usually some accompanying type of breathing dysfunction or severe cases of sinusitis.

White or pale nail beds show low vitality in the entire respiratory system. Be aware of breathing difficulties or excessive fatigue.

Pinkie Finger-Nail

The condition of pinkie fingernail bed represents the state of the endocrine (or glandular) system. Glands are the control centers of the body—regulating everything from heart rates to mental focus.  Some major glands are the pituitary, thyroid, thymus, adrenals, pancreas, and gonads.

Abnormal ridging is almost always related to behavioral or perceptive disorders.  Symptoms can be ADHD, Alzheimer’s, dementia, or schizophrenia.  Symptoms can also manifest as general malaise and lethargy.

Blue on the pinkie fingernail bed may be accompanied by bouts of anxiety, apprehension, or general uneasiness.

White on the pinkie fingernail bed may reveal diminished blood supply to the glandular system.  It can show up as lethargy, malaise, low energy and a negative disposition.
