Signs and symptoms of Maturity Onset Diabetes of the Young (MODY) tend to develop gradually. This is similar to the clinical course of type 2 diabetes, which develops slowly over a period of several months or years unlike type 1 diabetes in which symptoms develop rather quickly i.e. over a few weeks.
Symptoms of Maturity Onset Diabetes of the Young
Symptoms of MODY depend on the type of MODY such as people with MODY 2 have mild diabetes and minimal symptoms. Many people with MODY may have elevated blood sugar (hyperglycemia) for many years before they develop any symptoms. The high blood sugar may be diagnosed accidentally such as during a routine health check-up. In early stages, the person may have no symptoms, but without treatment, blood sugar will continue to rises thereby pulling the following symptoms:
- Increased thirst: rise in blood sugar levels causes the fluids to move out of the cells in the body. The loss of fluid from the cells makes one feel thirsty and therefore, a person with such a diabetic condition drinks more water.
- Frequent urination: rise in blood sugar causes fluids to move out of the cells and you to drink more fluid. When you drink more fluid, you are likely to urinate more frequently. The increased frequency of urination is present both during the day and at night.
- Increased hunger: in diabetes, there is plenty of sugar in the blood, but the cells of the body fail to use it due to a lack of insulin; this gets the cells deprived of an energy source and therefore, the patient feels hungry more frequently.
- Weight loss: as glucose (blood sugar) is not used efficiently and spills into urine from the blood, it causes loss of nutrient from body and weight loss (though appetite often increases).
- Blurred vision: Elevated glucose levels in the blood leads to loss of fluid from the lenses of the eyes thereby, affecting your ability to focus and see clearly.
- Other symptoms: Symptoms that may be present in a person with MODY are dry and itchy skin, fatigue or drowsiness. In some type of MODY such as MODY 5 (a rare type of MODY), other organs apart from pancreas such as kidneys may be affected. In many patients with MODY 5, kidney disease may be diagnosed before diabetes.
