Therapist and nutritionist Olga Burlakova said that sudden weight loss can indicate an ulcer, the presence of parasites in the body, thyroid problems, diabetes and cancer, News.ru reports. "It is worth noting that a sharp decrease in body weight can also be a consequence of such a serious illness as HIV. People who have encountered it may, among other things, experience pain in the muscles and throat, as well as suffer from various types of rashes," - added the specialist. Burlakova emphasized that a sharp weight loss can also be a result of tuberculosis, which is accompanied by a decrease in appetite, night sweats, chronic fatigue and prolonged coughing. According to the therapist, in middle and old age, sudden weight loss may be due to the onset of dementia due to the accumulation of beta-amyloids in the brain, which disrupt the mechanism of body weight regulation. Depression can also affect weight, the specialist said. "Food is a basic need that brings pleasure. In depression, joy does not bring anything. Eating is perceived as an additional obligation. And a person does not feel physiological hunger either, because depression disrupts the work of those parts of the brain that are responsible for appetite. It should be noted that a person often may not associate his psychological state with a sharp weight loss, "said anti-crisis psychologist Natalya Nikiforova. She stressed that for recovery, one should change the environment or take a day off for a few days. If depression occurs regularly, then the specialist advised to understand yourself and find the reason that provoked the depression. Earlier, doctors from the United States named six symptoms that indicate a dangerously high level of blood pressure, which requires immediate medical attention. They referred to them as severe headache, weakness or numbness, shortness of breath, blurred vision. With a regular increase in blood pressure, doctors advise changing dietary habits by reducing salt intake. Also, experts recommend exercising, eating more fruits and vegetables, nuts, legumes and low-fat dairy products.
