How does cancer starve organs?

Cancer cells have an insatiable appetite for nutrients, and they can divert the body's resources away from healthy organs. This process, known as cancer cachexia, can lead to malnutrition, weakness, and fatigue.

Cancer cells require a large amount of glucose, amino acids, and other nutrients to fuel their rapid growth. They can take up these nutrients from the bloodstream, or they can produce them themselves by breaking down proteins and fats.

In addition to consuming resources, cancer cells can also release substances that interfere with the absorption and utilisation of nutrients by healthy cells. This can further contribute to malnutrition and the development of cachexia.

As cancer progresses, cachexia can become more severe and can eventually lead to organ failure and death.

Here are some ways that cancer can starve organs causing organ failure:

• By competing with healthy cells for nutrients. Cancer cells grow and divide rapidly, so they need a lot of nutrients to do this. They can take these nutrients away from healthy cells, which can lead to organ damage. For example, cancer cells can compete with the small intestine for glucose, which is needed for energy production. This can cause low blood sugar levels, which can lead to symptoms such as weakness, fatigue, and dizziness.

• By increasing the breakdown of proteins and fats. Cancer cells can release substances that cause the breakdown of proteins and fats. This can release free fatty acids into the bloodstream, which can damage the liver and kidneys. It can also cause the loss of muscle mass, which can lead to weakness and fatigue.

• By blocking the absorption of nutrients. Cancer can damage the lining of the digestive tract, which can make it difficult for the body to absorb nutrients from food. This can lead to malnutrition and further weight loss.

• By releasing harmful substances. Cancer cells can release substances that can damage the organs. It can make it difficult for them to function correctly, ultimately leading to organ failure.
