Answer:
Type 1 diabetes.
Step-by-step explanation:
Adam most likely has type 1 diabetes since he has symptoms such as thirst, weight loss, frequent urination, and tiredness, which are usually present when the pancreas does not produce insulin, the hormone that decreases glucose levels in the blood and allows it to enter the cells and the liver so that the body can work properly.
In type 2 diabetes, the symptoms may not be present or not be as strong as in type 1 diabetes. Besides, type 2 commonly appears in people who are 40 years old or older, while type 1 can appear at any age.
