Serious Warning Signs Of Stomach Cancer

Issues Swallowing

There are several ways in which the growth of a tumor in the stomach tissues can result in issues swallowing. The simple mechanical interference of the growing cancerous tissue from the top of the stomach into the esophagus can create a narrower path for food to reach the stomach. Cancerous tissue can grow outside of or into the esophageal tissues, which is where nerves responsible for swallowing are located.

When invasive cancerous tissues damage the nerves, they may not be able to signal to the correct muscles when to contract during swallowing. Cancerous tissues can invade the actual muscle tissues themselves and impair the muscle's ability to contract properly. When a muscle that is vital to swallowing cannot contract, the patient will experience difficulty swallowing.

Persistent Fatigue

There are a few reasons why persistent fatigue can develop in stomach cancer patients. Stomach cancer can cause problems and interference with the ability to digest and absorb food properly. When the nutrients and components of food are not digested, they are not absorbed. As a result, they cannot be used for cellular functions and operations. Without nutrients like glucose that come from the food consumed, the cells cannot produce energy for the body.

Another reason why stomach cancer can produce persistent fatigue is that cancerous cells are just like normal cells. They require glucose, oxygen, and other nutrients to carry out their malicious activities. Because cancerous cells multiply and grow out of control, they can consume the glucose and nutrients that healthy cells would otherwise use. When there is a shortage of energy being produced by the healthy cells in the body, the energy produced is relocated to cater to vital organs, instead of the limb muscles. It is this shortage of energy that causes persistent fatigue in stomach cancer patients.
