Your body is a very intelligent system. At the beginning of any disease, it tries to help you figure out the cause and possible ways to overcome it. Even small, barely noticeable changes in your body can tell you a lot about serious internal organ diseases.
Chapped lips
If your lips and mouth corners are cracking and you also feel muscle weakness, you find it difficult to focus and lose hair, it can be a sign that your body lacks vitamin B2. Try eating more dairy products, eggs, peanuts, peaches, pears, soybeans, tomatoes and cauliflower.
White plaque on your tongue
If you do not eat for a long period of time (for example, because of dieting), if you constantly get colds, you have probably also noticed a white plaque on your tongue. If you have also noticed that the edges of your tongue are red, it is very likely you have gastritis.
Dry mouth
This is a normal response of your body to stress. If it lasts for a long time, you may be lacking vitamin B3 (nicotinic acid). You can get this vitamin eating poultry, nuts, beef, and wheat germ. Sometimes a dry mouth is a consequence of salivary glands inflammation or a very early stage of diabetes.
Flaky skin
Often this is a sign that your body lacks vitamins A and B2. Adjust your diet, and your skin condition will improve very quickly. If your skin peels and it is also very itchy, make sure you see a doctor. There is a good chance that you have a serious fungal disease.
