Physical activity is defined as any bodily movement produced by skeletal muscles that requires energy expenditure[1]. Physical activity encompasses all activities, at any intensity, performed during the 24 hour day[2]. It includes exercise and incidental activity integrated into daily activity. This integrated activity may not be planned, structured, repetitive or purposeful for the improvement of fitness, and may include activities such as walking to the local shop, cleaning, working, active transport etc. The liver, an organ only found in vertebrates, detoxifies various metabolites, synthesizes proteins, and produces biochemicals necessary for digestion.[2][3][4] In humans, it is located in the right upper quadrant of the abdomen, below the diaphragm. Its other roles in metabolism include the regulation of glycogen storage, decomposition of red blood cells and the production of hormones.[4] Hepatitis is inflammation of the liver tissue.[3]Some people have no symptoms whereas others develop yellow discoloration of the skin and whites of the eyes, poor appetite, vomiting, tiredness, abdominal pain, or diarrhea.[1][2] Hepatitis may be temporary (acute) or long term (chronic) depending on whether it lasts for less than or more than six months.[1][5] Acute hepatitis can sometimes resolve on its own, progress to chronic hepatitis, or rarely result in acute liver failure.[6] Over time the chronic form may progress to scarring of the liver, liver failure, or liver cancer.[3] The usual treatment for hepatitis is bed rest, it is recommended in order to avoid relapse of liver disease or complications in the future. It is also important to follow a well-balanced diet and to drink plenty of fluids, particularly if you are experiencing diarrhea or vomiting. Hepatitis A and B usually go away on their own within a few weeks with supportive care. While it’s still contagious, people with hepatitis should remain secluded to avoid infecting others. It is important to stay home from work, school, and other activities. A person with hepatitis should use a separate bathroom if possible at home, keep his toothbrush away from the others in the household, and wash his hands in a separate sink. According to the Hepatitis B Foundation, your liver operates in much the same way as the engine in a car. Like an engine, your liver performs a number of functions that ensure other body processes run smoothly. Taking care of your

liver is essential to helping it function properly, especially if you suffer from liver disease. A component of good care is bed rest, which can improve symptoms while on acute stage. The current use of bed rest in the treatment of diseases of the liver is admittedly empiric. All observers have agreed that bed rest during the acute stage of hepatitis generally improves the immediate symptoms. Hepatic tenderness is less under conditions of rest, while increase in size and tenderness of the liver frequently occurs with ambulation. Laboratory evidence of worsening hepatic function often parallels the change in liver size and tenderness. In a study to determine if early ambulation was safe in acute viral hepatitis (AVH), 202 patients of uncomplicated AVH were prospectively randomised into two group. Group A (n=100) received conventional treatment with bed rest while group B (n=102) patients were ambulated as soon as their clinical symptoms abated and progressive clinical and biochemical recovery was noted. While mean recovery time in two groups was not significantlly different (28.8 vs 29.7 days), bed rest period in group B was significantly less (28.8 vs 8.6 days). Natural history of the AVH, clinical and biochemical findings and relapse rate over a follow up period of 14 to 16 months, were no different in the two groups. None of the patients developed chronic hepatitis. Early ambulation is there fore safe in uncomplicated AVH and can lead to enormous saving of manhours and hospital resources. The observations by the author pertain to activity undertaken during the early part of clinical illness [11] which is not the subject of debate in the present work. We too recommend that patients should preferably be kept in bed during the symptomatic early phase of illness. However, as the patient gradually improves, he reaches a point where clinical symptoms have subsided, his appetite is good and he wants to move about. At this stage, in spite of the fact that he continues to have icterus and mild rise in transaminases, we have permitted ambulation without any adverse subjective and objective developments.
