Cracks in the corners of the mouth are a problem that almost everyone has encountered at least once in their life. Cracks most often appear at the beginning of spring, when the body's defenses are exhausted, there is an acute lack of vitamins, etc.

Small cracks in the corners of the mouth, which sometimes cause very severe pain when trying to open the mouth, are better known among doctors as angular stomatitis. They can be caused by streptococci or yeast-like fungi Candida. Irritation in the corners of the mouth causes a lot of inconvenience to a person - it becomes more difficult to eat, especially salty, sour, spicy food causes very severe pain, it is difficult for a person to talk, the affected area constantly itches, burns, in addition, angular cheilitis spoils the appearance, making it untidy. Especially often angular cheilitis appears in small children, whose immune system is just forming. In addition, children tend to put everything in their mouth and taste it, which can lead to infection, especially if there are lesions on the skin in the lip area or on the oral mucosa.

Cracks in the corners of the mouth must be treated, otherwise unsightly crusts and bleeding ulcers may appear. But before starting treatment, it is necessary to determine the cause of the cracks, and there may be more than one.

Causes of cracks in the corners of the mouth

Streptococcus bacteria are the most common cause of angular cheilitis, and fungal bacteria, the so-called candidal cheilitis in the corners of the mouth, are a little less common.

Streptococcal angular cheilitis occurs as a result of small cracks, poor personal hygiene, dry skin, hypothermia or overheating, advanced carious processes in the oral cavity, braces, dentures, and the habit of licking lips.

Candidal angular cheilitis occurs as a result of infection by fungi of the genus Candida. Almost always, candidal angular cheilitis in the corners of the mouth is accompanied by candidiasis of the tongue or oral cavity. In nature, yeast-like fungi are widespread, they are present on fruits, vegetables, and dairy products. They live on the skin and mucous membranes, activating their pathogenic properties in the event of a weakened immune system. Cracks in the corners of the mouth are formed with immune deficiency, very often against the background of taking antibiotics, cytostatics, hormones, etc. Cracks in the corners of the mouth often bother HIV-infected people.

Angular cheilitis is caused by anemia, which is expressed by pale skin and conjunctivitis. Iron deficiency in the body is expressed by dry and rough skin, dull and brittle hair prone to falling out, weak nails (brittleness, dullness, etc.). Anemia can develop as a result of poor nutrition, gastrointestinal diseases, which leads to hypovitaminosis.

The mucous membrane of the lips can be affected as a result of a lack of vitamin B2 in the body, which occurs due to a sharp reduction in dairy products in the diet or chronic gastrointestinal diseases.

Long-lasting, frequently recurring cracks in the corners of the mouth can bother patients with diabetes. This disease disrupts metabolism, which leads to low resistance of the body to bacterial infections.

Why are there cracks in the corners of the mouth?

Cracks in the corners of the mouth can appear in almost every person, regardless of age. Cracks in the corners of the mouth most often bother with the arrival of spring, against the background of weakened immunity. The reasons for the appearance can be different, but usually it is a malfunction of the body, which occurs as a result of improper functioning of the internal organs. In this case, if at some point you felt that you have cracks in the corners of the mouth, you need to listen to your body, maybe this is a signal of a more serious problem.

Also, the cause of angular cheilitis is often bacteria, which are transmitted through kissing, using other people's personal things (lipstick, dishes). Small children often put everything in their mouths - this is how the infection gets in.

As a rule, cracks in the corners of the mouth begin to appear when the body's defenses are weakened, with a vitamin deficiency (more often in the spring). Often, people who suffer from cracks in the corners of the mouth have a vitamin B deficiency in their body. But there are many reasons for the appearance of cracks in the corners of the mouth - for example, cracks in the corners of the mouth can appear as a result of an allergic reaction to toothpaste or some foods, and an incorrect bite, braces or dentures can provoke irritation in the corners of the mouth. Therefore, before starting treatment, you need to find out the reason for the cracks in the corners of the mouth, because if you treat only cracks, ignoring the reason for their appearance, this will lead to constant relapses.

If you know for sure that the cause of cracks on the lips is not related to health or taking medications, and cracks in the corners of the mouth bother you again and again, you need to pay attention to your diet. Cottage cheese, cheese, beef, eggs (yolk), liver contain a sufficient amount of vitamin B, so regular consumption of such products will be an excellent prevention of cracks. You can also include plant foods in your diet - green beans, fresh peas, broccoli, bran, spinach, wheat, rye. You can take a course of biologically active supplements with brewer's yeast.

Lack of iron and zinc in the body can cause constant cracks in the corners of the mouth. To prevent the development of anemia, you need to eat as many nuts, potatoes, pomegranates, mushrooms, parsley, peaches, oatmeal, buckwheat, asparagus, and rye as possible. Eating liver, heart, and red meat will help increase the level of iron in the body. To replenish zinc reserves, you need to regularly eat seafood, eggs, pumpkin seeds, brewer's yeast, greens, and sprouted wheat grains.

Also, when angular cheilitis appears, you can take a course of vitamins that will help strengthen the entire body as a whole.

What to do if you have cracks in the corners of your mouth?

If the cracks in the corners of the mouth do not go away, even after certain treatment, it is necessary to take a scraping to identify the pathogen (streptococcus, staphylococcus, yeast-like fungi), and do a blood test to determine the level of vitamin B in the body.

If the cause of the angular cheilitis is a fungus, the doctor will prescribe antifungal drugs, the selection of which is carried out individually, taking into account the sensitivity to drugs and the characteristics of a particular disease.

Vitamins for cracks in the corners of the mouth

Cracks in the corners of the mouth may indicate a lack of vitamins in the body. In this way, our body lets us know that we need to pay attention to our diet. If there are no health problems, but cracks in the corners of the mouth periodically make themselves known, you need to take a course of vitamins, in particular those containing vitamin B2.

Vitamin B2, also known as riboflavin, helps our skin maintain a young and beautiful appearance. A deficiency of this vitamin can cause nervous disorders, breakdowns, digestive problems, gastritis, general malaise, various skin diseases, and decreased immunity.

Also, with angular cheilitis, the body experiences an acute shortage of iron and zinc. The lack of these microelements causes anemia. With anemia, the body experiences a shortage of red blood cells, the hemoglobin level decreases. As a rule, anemia develops as a result of insufficient iron. Strict diets, poor nutrition, in particular quick snacks on the go can lead to iron deficiency. In childhood, anemia often develops from excessive consumption of sweets and refusal of healthy foods. Therefore, the first symptom of iron deficiency in the body can be angular cheilitis in the corners of the mouth.

When choosing vitamins, you can buy a complete complex, which will also include vitamin B2, iron and zinc, or you can buy preparations separately, for example, B vitamins (it is imperative to pay attention to the vitamin complex to include vitamin B2) and preparations containing zinc and iron. Preparations with iron or zinc may also contain additional vitamins, for example, vitamin C, which activates the body's defenses, which will not be superfluous for cracks in the lips.

Prevention of cracks in the corners of the mouth

If you often have cracks in the corners of your mouth, you need to stick to a certain diet, which includes foods with a high content of vitamins B2, E, iron and zinc. You need to limit sweets, eat more vegetables and fruits. Reduce the consumption of smoked, salty, spicy, etc.

It is necessary to undergo a preventive examination by a dentist twice a year, because, as noted above, advanced dental caries can be the cause of regular cracks in the corners of the lips. It is necessary to ensure that dentures and crowns do not cause discomfort and are comfortable, because this can also lead to irritation of the mucous membrane and the appearance of cracks.

Dryness and peeling of the lips are the harbingers of angular cheilitis, so to prevent the appearance of angular cheilitis, you can use some tips:

Thermal water is an excellent preventative measure against angular cheilitis. To prevent cracks in the corners of the lips, simply moisten your lips with thermal water several times a day. Also, a hygienic lipstick based on thermal water will help very well.

A decoction of flax seeds will also help prevent angular cheilitis. To prepare the decoction, you will need 2 teaspoons of seeds and a glass of water. Boil the mixture over low heat until it becomes mushy and apply several times a day to the lips and corners of the mouth. You can also use any honey, which you can lubricate your lips with at night.

An interesting remedy that helps prevent angular cheilitis is a mixture of lard and rose petals (from one flower). Mix the petals with a tablespoon of lard, rub thoroughly, and lubricate your lips with the resulting mixture.

Cracks in the corners of the mouth can appear at any age, both in men and women. In this case, the main thing is timely and effective treatment. An inflammatory process left to its own devices will eventually affect more and more areas of the skin, deep cracks and bleeding ulcers may appear. The sooner treatment is started and the cause of cracks in the corners of the mouth is determined (vitamin deficiency, weak immunity as a result of illness or taking medications, caries, etc.), the more effective and faster the recovery will be. Eliminating the cause of cracks in the corners of the mouth will rid you of this unpleasant disease for a long time.
