Stomach flu, medically known as viral gastroenteritis, is an unpleasant experience characterized by symptoms like nausea, vomiting, diarrhea, and abdominal discomfort. Many people wonder, "How long does stomach flu last?" The duration of stomach flu can vary from person to person and depends on several factors.

Typically, stomach flu lasts for about 1 to 3 days, although some cases may resolve within 24 hours. The acute phase of the illness, which includes intense symptoms, often peaks during the first 24 to 48 hours. After this period, symptoms gradually start to improve, and most people recover without any specific treatment.

However, the complete recovery timeline can be influenced by various factors. The type of virus causing the infection, an individual's overall health, and how well they stay hydrated during the illness can all impact the duration. In some cases, particularly severe or prolonged stomach flu, symptoms may persist for up to a week or more.

Staying hydrated is crucial during stomach flu, as vomiting and diarrhea can lead to significant fluid loss. Replenishing lost fluids and electrolytes is vital for a quicker recovery. If symptoms persist beyond a week or become more severe, it's essential to consult a healthcare provider, as it might be a sign of a more serious issue.

In summary, the duration of stomach flu varies, with most cases resolving within 1 to 3 days. Proper hydration and rest can help you recover faster, but if symptoms persist or worsen, seek medical advice to rule out any complications.
