Sinusitis is a disease caused by inflammation of the paranasal sinuses. As a result, the nasal mucosa increases in size and blocks the pathways for the outflow of serous fluid. When the patient is inactive, the clogged bacteria begin to amplify and fill the sinuses with pus. Adults and children are susceptible to this illness. The peak incidence is observed with the onset of cold weather in the autumn-winter period. Leaning forward aggravates many of the symptoms. Therefore, if the first symptoms of the disease are detected, make an urgent appointment for sinusitis treatment with us. KSD will help not only get rid of the manifestations of the disease, but also eliminate its root cause. If the patient is inactive, the illness can become chronic. At the initial stage, it seems to the patient that the disease is receding. Symptoms subside, and some symptoms appear only in the supine position. In some cases, chronic sinusitis does not make itself felt for years, but at this time, the neglected disease has a detrimental effect on the heart, kidneys, lungs and liver.
