The Pancreas in Chinese Medicine:
Integrated in the Spleen–Stomach System

 

Pancreas in TCMIn Western medicine, the pancreas is a gland located behind the stomach with two main roles. Its exocrine function is to secrete digestive enzymes into the small intestine to break down fats, proteins, and carbohydrates. Its endocrine function is to produce hormones, including insulin, which regulates blood sugar. Pancreatic disorders, such as diabetes or pancreatitis, are considered serious and often life-threatening. Yet the pancreas is rarely thought of beyond its chemical contributions to digestion and metabolism.

Strengthening the Spleen–Stomach System

The Spleen and Stomach correspond to the Earth element and are most active in late summer, the time of harvest and abundance. Supporting this system helps improve digestion, energy, and mental clarity.

Tips for Supporting the Spleen–Stomach:

  • Eat warm, cooked meals – Soups, stews, steamed grains, and lightly cooked vegetables are ideal.
  • Keep mealtimes regular – Avoid skipping meals or eating late at night, which can weaken the Spleen.
  • Reduce sweets and cold foods – Too much sugar or raw foods can create dampness and slow digestion.
  • Manage stress – Chronic worry or overthinking drains the Spleen's energy. Practice calming exercises or take quiet breaks.
  • Eat mindfully – Chew thoroughly, avoid distractions, and appreciate the nourishment in each bite.

Caring for the Spleen–Stomach helps keep your center strong, supporting both body and mind.

In Traditional Chinese Medicine (TCM), there is no separate concept of the pancreas as a distinct organ. Instead, its functions are integrated into the Spleen–Stomach axis, the central pair of the zàng-fǔ system responsible for digestion, transformation of nutrients, and distribution of energy. The Spleen and Stomach are viewed as complementary: the Stomach "receives and ripens" food and drink, while the Spleen "transforms and transports" the essence of nourishment throughout the body.

Many of the functions that Western medicine assigns to the pancreas such as regulating blood sugar, assisting digestion, distributing energy, fall under the domain of the Spleen in TCM. This highlights a key difference in worldview: TCM organizes bodily functions into broader systems of interaction rather than separate, isolated organs.

The Spleen governs the transformation of food into qì and blood, distributes energy to the limbs and tissues, and keeps blood circulating properly. A weak Spleen can lead to fatigue, muscle weakness, poor appetite, loose stools, and even prolapse of organs. From the Western perspective, many of these symptoms might be linked to pancreatic insufficiency, hypoglycemia, or malabsorption syndromes.

The Stomach, on the other hand, is responsible for receiving and breaking down food, providing the raw material for the Spleen to work with. It corresponds to the "rotting and ripening" of food, similar to the initial stages of digestion. Together, the Spleen and Stomach embody the Earth element, providing stability, nourishment, and the ability to transform what is taken in into usable energy.

Emotionally, the Spleen is associated with thought and worry. Overthinking, pensiveness, or mental strain can damage the Spleen's ability to transform and distribute energy, leading to fatigue and digestive problems. The Stomach reflects our ability to receive and process life's experiences, while the Spleen allows us to extract what is valuable and let the rest go.

The TCM approach to conditions like diabetes, which in Western medicine is seen as a pancreatic disorder, focuses on tonifying the Spleen and harmonizing the Stomach while regulating fluids and addressing excess heat. Herbs, acupuncture, and lifestyle practices are chosen to support the overall digestive and metabolic system rather than targeting a single gland.

The Spleen–Stomach axis is also sensitive to extremes of diet, temperature, and emotional stress. Cold or raw foods, excessive sweets, irregular eating, and chronic worry can all damage this system. Caring for it involves regular meals, warm and cooked foods, and cultivating a calm and focused mind.

In TCM, the pancreas is not forgotten... it is simply understood as an integral part of the body's center of nourishment, housed within the dynamic relationship between Spleen and Stomach. This reflects a holistic view that prioritizes balance and interaction over anatomy alone.
