[18F] Experiencing fatigue, rapid heart rate, polyphagia, polydipsia, and weight loss

What might be happening

Based on the symptoms you've described, here are some possible conditions:

• Type 1 Diabetes: This is a condition where your body doesn't produce enough insulin, a hormone that regulates the amount of sugar in your blood. Symptoms can include increased thirst and hunger, frequent urination, unexplained weight loss, fatigue, and blurred vision. This condition is often diagnosed in children and young adults, so your age fits with this possibility.

  • To confirm this diagnosis, a doctor would need to perform blood tests to measure your blood sugar levels and possibly your insulin levels. If you do have Type 1 Diabetes, you would need to take insulin injections and monitor your blood sugar levels regularly.

• Hyperthyroidism: This is a condition where your thyroid gland produces too much thyroid hormone. Symptoms can include rapid heart rate, weight loss, increased appetite, and fatigue. You mentioned a family history of thyroid problems, which can increase your risk of developing this condition.

  • To confirm this diagnosis, a doctor would need to perform blood tests to measure your levels of thyroid hormones. If you do have Hyperthyroidism, treatment options include medication, radioactive iodine, and surgery.

What you can do

You should seek medical attention as soon as possible. These conditions can be serious if left untreated, but they can be managed effectively with the right treatment. In the meantime, try to maintain a balanced diet and stay hydrated.
