Is there any medicine or therapy can open her digestive system and ease the comprassion on her lower body so she can start eating and walk again on her own for better chance of her system to fight the disease?? Thanks
[|AI|]  Loss of appetite in cancer patients is due to poor intake by cancer patients as they will not be able to take adequately due to lack of appetite. Also, the nutritional demands are high as the cancer cells have rapid turnover. Swelling is because of compression over blood vessels Chat Doctor.  Also low intake of protein causes body swelling. Her condition can be improved by 1) good nutrition including high calorie and high protein diet. Certain medications can help improve appetite 2) If the tumor regresses in size, pressure effects would decrease and limb swelling would decrease. This can be achieved by chemotherapy
