The intake of excessive sugar is associated with multiple health complications, including cancer. The cells in the body, including cancerous ones, use glucose to survive, grow and spread. Glucose may not be directly responsible for the onset of cancer. However, having sugar in excessive amounts may increase the risk of the disease and worsen its symptoms. So, here is a look at how high sugar intake can worsen common symptoms of cancer:

Fatigue
Sugar can help temporarily boost energy levels. The pancreas produces enough insulin to break down food into simple sugars, which are then utilized by cells to stay energized. However, sometimes the pancreas may not be able to produce enough insulin, which could lead to excessive sugar in the blood, causing fatigue and weakness. Further, if one is at risk for cancer or is affected by the disease, the body needs more energy to fight the abnormal cells. So, fatigue is a common sign of cancer that can worsen when dealing with high blood sugar.

Frequent infections
If one is dealing with cancer, the weakened immune system is already prone to frequent infections. The immune system requires balanced nutrition, such as healthy amounts of minerals and vitamins, to thrive and fight diseases, including cancer. However, when cancerous cells spread, they may prevent the immune system from absorbing these nutrients. Further, sugar encourages the production of inflammatory proteins, making one more susceptible to illnesses.

Frequent pain
One may usually experience pain for reasons including strenuous exercises or injuries. However, the symptom is an early sign of cancer. Cancerous developments may often press against the nerves across areas of the body, which could lead to pain. Further, sugar can worsen the pain by triggering inflammation. So, when experiencing persistent pain, one should consult a doctor to determine the underlying causes and if limiting sugar intake might be the solution.

Constipation
Gastrointestinal complications like constipation can be symptoms of cancer. So if one is dealing with the disease, excessive sugar intake can worsen constipation. Further, type 2 diabetes, which is associated with frequently high blood sugar, may create an environment in the colon for cancer to grow easily. This puts one at a higher risk of colorectal cancer than those who do not have diabetes.
