Diabetes mellitus is a metabolic disorder which is characterized by hyperglycemia or high glucose level in the blood. It occurs due to disturbances of carbohydrates, fats, and metabolism of proteins which results from insulin secretion, insulin action, or both. Normally, the organ pancreas makes the insulin which helps the glucose to spread in all the cells in the body. Diabetes mellitus develops when the body fails to make enough insulin or when the body fails to use produced insulin effectively. In such cases, there is a build-up of sugar in the blood.
Diabetes mellitus is associated with a wide range of symptoms and increased thirst is one of the common symptoms. Other symptoms of diabetes mellitus may include increased urination, fatigue, blurred vision, very dry skin, more infections than usual, and slow wound healing. Diabetes mellitus is a serious disorder which is not a single disease, but it is a disease which is characterized by hyperglycemia and over time, it increases the risk of developing problems to eyes, kidney, nerves, and the heart. There are various factors that increase the risk of developing diabetes mellitus such as stress, obesity, and genetics. Genetics is one of the most common causative factors of diabetes mellitus.
2. Kidney Failure
Kidneys play a vital role in the human body and they are responsible for eliminating waste products from the body, through the urine and it also helps to maintain normal electrolyte and fluid balance within the body. Kidney failure is a condition which occurs when the kidneys fail to function normally. Normally, the waste products that are excreted from the body by the kidneys, but when kidneys fail to function, there is a buildup of waste in the bloodstream. This results in the occurrence of symptoms associated with kidney failure.
The symptoms of kidney failure vary from one person to another and it depends on the stage and severity of the disease. Most often, patients having renal failure and are in the early stages of chronic renal failure tend to first develop an increased thirst and increased urination. As the disease progresses, other symptoms may also develop such as loss of appetite, weight loss, vomiting, bad breath, and mouth ulcers, electrolyte abnormalities, high blood pressure, anemia, and poor body condition. As the kidneys can no longer excrete waste products out in the urine and these wastes build up in the blood and this condition is known as uremia.
3. Alcohol-related liver disease

Alcohol-related liver disease is one of the leading cause of liver disease and is responsible for significant morbidity and mortality.

Acute alcoholic hepatitis is the second stage and it is the condition in which the inflammation occurs and the condition becomes quite serious. Alcoholic cirrhosis is the last and final stage which is life-threatening and results in liver failure. The histological abnormality that occurs with alcohol-related liver disease can range widely from steatosis to hepatocellular carcinoma. Patients having this alcohol-related liver disease are at high risk of developing hepatic steatosis, steatohepatitis, cirrhosis, and hepatocellular carcinoma.
4. Dry mouth
