COVID-19, caused by the SARS-CoV-2 virus, presents a wide array of symptoms. Among these, changes in appetite, often leading to a reduced desire to eat, are frequently observed. This symptom can significantly impact a person’s well-being during illness and recovery.
How COVID-19 Impacts Your Appetite
Appetite loss is a common COVID-19 symptom, stemming from several interconnected biological and symptomatic factors. The virus’s impact extends beyond the respiratory system, influencing various bodily functions that regulate hunger and food intake.
Appetite changes often stem from the loss or alteration of taste and smell. SARS-CoV-2 affects cells in the nasal cavity and taste buds, diminishing food’s pleasure and appeal. Food may become bland or unappetizing, making eating an unappealing task. This sensory impairment can be an early sign of infection and contributes to a decreased desire to eat.
The body’s immune response also plays a role in appetite suppression. When SARS-CoV-2 enters the body, it triggers the release of signaling molecules called cytokines. Elevated levels of these inflammatory cytokines interfere with the brain’s appetite-regulating centers, leading to a reduced sensation of hunger. This systemic inflammation can alter metabolism and contribute to a disinterest in food.
Gastrointestinal (GI) issues also commonly suppress appetite. The virus can invade cells lining the digestive tract, causing inflammation and symptoms such as nausea, vomiting, and diarrhea. These discomforts make eating unappealing and can make it difficult to keep food down. Appetite loss is reported as a common GI symptom, occurring in up to 50% of confirmed cases.
General fatigue and malaise also indirectly affect appetite. Feeling profoundly tired, weak, or unwell can make preparing and consuming food seem overwhelming. This pervasive exhaustion can reduce motivation for all activities, including eating, leading to decreased food intake.
Beyond physical symptoms, psychological factors influence appetite during COVID-19 illness. Stress, anxiety, and isolation from being sick or quarantined can disrupt normal eating patterns. Emotional distress may suppress appetite or change eating habits due to the illness’s mental burden.
Navigating Appetite Changes During Illness
Maintaining adequate nutrition and hydration is important for recovery, even with reduced appetite. Focusing on fluids is a primary step, as dehydration can worsen symptoms and hinder recovery. Drinking water, broths, and electrolyte-rich beverages regularly helps replace lost fluids and support bodily functions. Small, frequent sips are often more manageable than large quantities.
Prioritizing small, nutrient-dense meals helps ensure the body receives necessary energy and building blocks. Easily digestible foods like plain rice, toast, soups, bananas, and applesauce are often well-tolerated. Incorporating protein sources, such as lean meats, eggs, or dairy, also supports the immune system and prevents muscle loss.
For those experiencing changes in taste and smell, experimenting with different food textures, temperatures, and flavors can make eating more appealing. Some find bland foods more palatable, while others prefer stronger flavors from herbs or spices. Cold foods might be better tolerated than hot ones, as their flavors can be less intense. Focusing on the overall feeling after eating, rather than just taste, can also be helpful.
Rest is also a component of managing illness and supporting recovery, which indirectly aids appetite. Allowing the body sufficient time to rest conserves energy and helps the immune system combat the virus. This can alleviate fatigue that makes eating difficult.
Recognize when professional medical consultation is necessary. If appetite loss is persistent or severe, or accompanied by significant weight loss, signs of dehydration (such as dark urine or extreme thirst), or an inability to keep any food or liquid down, seek medical advice. These signs indicate a need for a healthcare provider to assess the situation and recommend interventions.
