The feeling of heaviness and pulling pain in the lower abdomen, increasing by the end of the working day, may indicate a violation of alert flow in the small pelvis, said the obstetrician-gycologist of the RUDN University Hospital, candidate of medical sciences in Karnapova. The cause of the problem may be a violation of the work of the poison valve, a decrease in the elasticity of blood vessels or their compression by neighboring anatomical structures. Other risk factors are repeated births, multiple pregnancies, having a large child. Tight clothes (tight belt, tight jeans) increase the problem: creates pressure in the internal area, stimulates sweating and the risk of infections. Another factor is a sensitive lifestyle (including long-term computer work). For prevention, it is important to regularly change the position of the body and take breaks for heat. With constant pain, you should consult a doctor - the symptoms can indicate various diseases. Photo: istockPhoto.com Subscribe to AiF. Health at Max.
