Suspected diabetes mellitus?
Hello Doctor: I recently discovered that I have a problem with excessive drinking, but I don't urinate often.
I also feel sleepy after eating.
A few weeks ago, I had blood tests and a urinalysis to check my blood sugar, but only the fasting blood sugar was tested, which was 95.
The doctor said it was normal.
However, I noticed a lot of ants crawling around the toilet recently, which makes me very worried that I might have diabetes.
I would like to ask the doctor if this means I might have diabetes or another condition? Do I need to see a doctor again?

More Info
It's understandable to have concerns about diabetes, especially when you notice symptoms that could be indicative of the condition. Based on your description, you are experiencing increased thirst, fatigue after meals, and have observed ants around your toilet, which may suggest the presence of sugar in your urine. These can be signs of diabetes, but they are not definitive on their own.
Firstly, let's discuss the symptoms you mentioned. Increased thirst (polydipsia) and fatigue after eating (postprandial fatigue) can indeed be associated with diabetes, particularly if your body is struggling to manage blood sugar levels effectively. In diabetes, the body either does not produce enough insulin (Type 1) or does not respond properly to insulin (Type 2), leading to elevated blood glucose levels. When blood sugar levels are high, the kidneys may excrete excess glucose into the urine, which can attract ants, as they are drawn to sugar.
Your blood glucose reading of 95 mg/dL before a meal is within the normal range, as normal fasting blood glucose levels are typically between 70 and 100 mg/dL. However, it’s important to consider that diabetes can sometimes present with normal fasting glucose levels, especially in the early stages or in cases of insulin resistance. Therefore, it would be prudent to monitor your blood sugar levels more closely, including postprandial (after eating) readings, to get a clearer picture of your glucose metabolism.
Given your concerns, it would be wise to follow up with your healthcare provider. They may recommend additional tests, such as an oral glucose tolerance test (OGTT) or a hemoglobin A1c test, which provides an average blood glucose level over the past two to three months. These tests can help determine if you are at risk for diabetes or if you have already developed the condition.
In addition to testing, consider discussing your symptoms in detail with your doctor. They can help assess whether your symptoms are related to diabetes or if they might be due to another condition, such as hormonal imbalances, stress, or dietary factors.
It's also essential to adopt a healthy lifestyle, which includes a balanced diet, regular physical activity, and maintaining a healthy weight. These factors can significantly influence your risk of developing Type 2 diabetes and can help manage blood sugar levels if you are already diagnosed.
In summary, while your current blood sugar reading is normal, your symptoms warrant further investigation. It’s advisable to consult your healthcare provider for a comprehensive evaluation and to discuss your concerns. Early detection and management of diabetes can prevent complications and improve your overall health. Remember, being proactive about your health is key, and seeking medical advice is a positive step in addressing your concerns.
