Diabetes and cancer may also be associated with stress.

Type 2 diabetes, a chronic illness characterized by insufficient insulin production by the pancreas, increases the risk of Alzheimer's disease. Interestingly, memory loss tends to progress more slowly in diabetic Alzheimer's patients than in non-diabetic Alzheimer's patients.

In middle-aged individuals with Type 2 diabetes, mental decline may be worsened by stress. Men who experience persistent stress have a 45% higher likelihood of developing diabetes compared to those with little to no stress.

Similarly, although stress does not directly cause cancer, it can contribute to cancer progression by weakening the immune system's ability to suppress the release of natural killer cells, thereby reducing the body's defense against the growth of cancer cells.

During stress, the release of adrenaline interferes with a protein that normally restricts cancer cell growth, potentially enhancing cancer spread.

Studies indicate that individuals facing significant stress or bereavement within a year have an increased risk of cancer.
