Obesity is considered one of the biggest risk factors for complications from COVID-19. American scientists have found that being overweight can also increase the risk of contracting coronavirus. According to medportal.ru, patients with a high body mass index (BMI) often have respiratory dysfunction, in which unwanted changes in respiratory mechanisms occur, increased airway resistance, impaired…
A tube inserted into the nostrils to dull the sense of smell may be an effective new method of weight loss. People on a strict diet and using this device for three months lost twice as much weight as those who were just on the diet, Obesity Facts reported. According to The Daily Mail, the…
