"Usually, in the spring-autumn period, several major chronic diseases are exacerbated. First, these are diseases of the gastrointestinal tract: chronic gastritis, enteritis, colitis, gastric ulcer and duodenal ulcer. This happens for various reasons: weakened immunity, lack of vitamins, changes in acidity, stress, "explained Elena Popova, Deputy General Director for Medical Activities, Chief Physician of INVITRO-Stavropolye.

According to her, spring is a transitional period, including for the body.

"This is due to the nature of nutrition: in winter and early spring, there are fewer fruits and vegetables in the diet, so in the spring we may lack vitamins and elements necessary for the natural renewal of the gastric mucosa. Some people begin to follow strict diets to lose weight by the summer, which further reduces the activity of the immune system, chronic stress occurs, "she added.

These factors lead to an increase in the production of hydrochloric acid in the stomach with a subsequent damaging effect on its mucosa, Popova emphasized.

In addition, a weakened immune system, hormonal disruptions, active flowering of plants lead to exacerbations of allergies, the therapist recalled.

She explained that in the spring the air becomes warmer, the flowering of grasses begins, which means that the content of dust, pollen, seeds, fluff and other substances dangerous for asthmatics increases sharply.

"It is not surprising that spring is the time of exacerbation of bronchial asthma. Pulmonologists recommend that patients with bronchial asthma in the spring especially carefully take the prescribed funds, and when symptoms of respiratory deterioration appear, do not postpone a visit to the attending physician, "the expert noted.

To prevent exacerbations of diseases of the digestive tract, it is necessary to follow a sparing diet, eat right, regularly take medications prescribed by the attending physician, try to exclude products that damage the mucosa.

Earlier, the most common types of allergies among Russians were named.
