Do You Lose Weight From COVID? Causes & What to Do

COVID-19, caused by the SARS-CoV-2 virus, presents with a wide range of symptoms and varying severity. It affects various bodily functions beyond the respiratory system. Manifestations range from asymptomatic cases to severe illness requiring hospitalization.

Is Weight Loss a Common Symptom?

Weight loss is common for many with COVID-19, especially during the acute phase. This is often due to the body’s response to the viral infection and its symptoms. Weight loss varies based on infection severity and overall health. Studies show many COVID-19 patients experience significant weight loss, sometimes exceeding 5% of their initial body weight. This affects individuals whether hospitalized or recovering at home.

How COVID-19 Can Lead to Weight Loss

Several physiological mechanisms explain COVID-19 related weight loss. The body’s immune response increases metabolic rate, burning more calories to fight the illness, especially with fever. This heightened energy demand can cause weight loss if caloric intake does not match expenditure.

Common COVID-19 symptoms like loss of taste and smell reduce appetite and food intake. Unappealing food reduces intake, causing a caloric deficit and weight loss. Gastrointestinal issues like nausea, vomiting, and diarrhea are common, reducing nutrient absorption and caloric intake. These symptoms can also lead to dehydration.

Inflammation and cytokine storms, severe immune responses, place extreme metabolic demands on the body. This hyper-inflammatory state exacerbates muscle wasting, known as sarcopenia, where the body breaks down muscle tissue for energy. Immobility during illness, coupled with inflammation, further contributes to this loss of muscle mass, a component of overall weight.

Psychological factors, including stress and anxiety, also impact eating habits. While some may eat more due to stress, others find their appetite suppressed, reducing food intake. This complex interplay of physical and psychological stressors contributes to unintentional weight loss in many COVID-19 patients.

Supporting Recovery and Managing Weight Changes

Prioritize nutrition for COVID-19 weight loss recovery, focusing on nutrient-dense foods in smaller, more frequent meals. Adequate hydration is also important. For persistent significant weight loss, consult a healthcare professional or dietitian for personalized guidance and supplements.

Gradual physical activity is important to rebuild strength and muscle mass. Begin with light activities, slowly increasing intensity and duration. Avoid overexertion to prevent setbacks and support steady recovery.

Monitor weight changes and symptoms. Seek medical advice for rapid, unexplained weight loss, persistent post-recovery symptoms, or inability to eat. Professional consultation is important if severe fatigue or fever accompany weight loss. Recovery takes time; patience and self-care are important for regaining health.
