Poor Appetite and Weight Loss — When Eating No Longer Gives You Energy

Even eating itself feels exhausting

This is a state in which appetite drops without any specific underlying disease, weight decreases despite eating, and energy declines along with it. It is common in older adults, patients with chronic illness, postoperative patients, and those under prolonged stress.

Korean medicine diagnosis: Spleen qi deficiency (脾氣虛)

In Korean medicine, the Spleen (脾) is the root of the postnatal constitution (後天之本), transforming food into qi and blood. When Spleen qi is deficient, food cannot be converted into energy even after eating.

• Spleen qi deficiency: Loss of appetite, indigestion, loose stools, fatigue → Sagunja-tang (四君子湯)
• Spleen-Stomach deficiency cold: Cold abdomen and diarrhea after cold foods → Yijung-tang (理中湯)
• Dual deficiency of qi and blood: Loss of appetite plus dizziness and pale face → Paljin-tang (八珍湯)

Acupuncture and moxibustion

Zusanli (ST36) is the prime acupoint for the digestive system and directly boosts Spleen-Stomach function. Moxibustion on Zhongwan (CV12) replenishes stomach yang and helps appetite begin to recover.

Eating habits to restore appetite

• Do not try to eat large amounts at once — have small portions frequently (5–6 times a day)
• Start with warm porridge or thin gruel and gradually increase the amount
• A light walk before meals stimulates appetite
• Choose cooked foods rather than cold or raw items such as fruit or vegetable juices
