[18F] Experiencing weakness, polydipsia, polyphagia, and blurred vision

What might be happening

Based on the information you've provided, the following conditions could be causing your symptoms:

• Diabetes: This is a condition where your body either doesn't produce enough insulin or can't effectively use the insulin it does produce. This can lead to high blood sugar levels, which can cause symptoms like increased thirst and urination, unexplained weight loss, fatigue, and blurred vision.

• Hyperthyroidism: This is a condition where your thyroid gland produces too much thyroid hormone. This can speed up your metabolism, causing unexplained weight loss, rapid or irregular heartbeat, sweating, and irritability or nervousness.

• Anemia: You mentioned you have a history of anemia, which can cause fatigue and weakness. However, it doesn't typically cause the other symptoms you're experiencing.

What you can do

Given your symptoms, it's important that you see a healthcare provider as soon as possible. They can perform tests to determine what's causing your symptoms and recommend appropriate treatment. In the meantime, try to maintain a balanced diet and stay hydrated.

What you should look out for

If you experience any of the following symptoms, seek medical attention immediately:

• Severe dehydration symptoms such as very dry skin, dizziness, or fainting
• Rapid or irregular heartbeat
• Changes in your level of consciousness

Remember, this advice is intended to be general in nature, and specific causes may not apply to your situation. Always consult with a healthcare provider for appropriate examination, testing, and care.
