Uncontrolled Diabetes and HIV Infection
Oral thrush is common in people with diabetes. This is because high sugar levels can aid the growth of yeast and cause poor resistance to infection. Diabetes causes a dry mouth that also has a higher amount of sugar glucose in the saliva, and this condition makes it favorable for thrush growth. If this cause of oral thrush is not treated immediately, it can lead to more ulcers.
Oral thrush can also be traced to HIV patients. When one has HIV, the immune system is weakened, which makes it hard for the immune system to fight against the infection. Oral thrush is usually among the first symptoms of HIV. And also a sign that you are at the risk of developing more infections.
