Cheilitis
If you have cracks at the corner of your mouth, you may be suffering from a common condition known as angular cheilitis. This is a fungal infection; if left unchecked, it can often lead to a fully-blown infection of the mouth. It may indicate: poor diet, deficiency of iron as well as of Vitamin B-2 (Riboflavin), B3 (Niacin), B-6 (Pyridoxine) and B-12 (Cyanomobalamin). Or, it could be because of ill-fitting dentures. This can cause ‘over-closure of the mouth due to which saliva builds up in the corners of the mouth, favouring a bacterial or fungal infection. Cheilitis may also mean that you are allergic to toothpastes or cosmetics; your pen-biting habit can also be a cause.
Dark circles
Dark circles are blemishes around the eyes. It is also known as eye bags or raccoon attack. There are many causes behind this symptom, including heredity. Some of the causes are: lack of oxygen in the tissues; anaemia or deficiency of iron (you are more susceptible to iron deficiency during pregnancy and menstruation); or lack of sleep or excessive fatigue—this can lead to pale skin, making the blood underneath the skin to become more visible and thus appear bluer or darker.
Nails
Nails are a skin appendage; they have their own signs and symptoms which may relate to other medical conditions. Nail changes may signify a number of disorders elsewhere in the body. These changes may indicate illness long before any other symptoms appear.
Some of the symptoms and what they indicate are:
• Brittle nails signify possible iron deficiency, impaired kidney function and circulation problems.
• Brittle, soft, shiny nails with a moon may indicate an overactive thyroid.
• Dark nails and/or thin, flat, spoon-shaped nails are a sign of Vitamin B12 deficiency or anaemia. Nails can also turn grey or dark if it touches chemicals (most often bleach) or a substance to which one is allergic.
• Deep blue nail beds show a pulmonary obstructive disorder such as asthma or emphysema.
• Greenish nails, if not a result of a localised fungal infection, may indicate an internal bacterial infection.
• Black, splinter-like bits under the nails can be a sign of the infectious endocarditis, a serious heart ailment; other heart disease; or a bleeding disorder.
• A half-white nail with dark spots at the tip indicates possible kidney disease.
• An isolated dark-blue bank in the nail bed, especially in light-skinned people, can be a sign of skin cancer.
• Nail beading (the development of bumps on the nail surface) is a sign of rheumatoid arthritis.
• Nails that chip, peel, crack, or break easily show a general nutritional deficiency and the insufficiency of hydrochloric acid and proteins. Minerals are also needed.
• Ridges can appear on the nails either vertically or horizontally. Vertical ridges indicate poor general health, poor nutrient absorption, and/or iron deficiency; they may also indicate a kidney disorder. Horizontal ridges can occur as a result of severe stress, either psychological or physical, such as from infection and/or disease.
• White lines across the nail may indicate a liver disease.
• If the white moon area of the nail turns red, it may indicate heart problems; if it turns slate blue, then it can indicate either heavy-metal poisoning (such as silver poisoning) or lung trouble.
• White nails indicate possible liver or kidney disorders or/and anaemia.
• White nails with pink near the tips are a sign of cirrhosis.
• Yellow nails or an elevation of the nail tips can indicate internal disorders long before other symptoms appear. Some of these are problems with the lymphatic system; they may also mean respiratory disorders, diabetes, and liver disorders.
• Nail ends that curve downward may denote heart, liver or respiratory disease
