[18F] Experiencing blurred vision, lightheadedness, and fatigue

What might be happening

Based on the symptoms you've described, the following conditions could be possible:

• Orthostatic Hypotension: This condition is characterized by a sudden drop in blood pressure when you stand up from a sitting or lying position, leading to symptoms like dizziness, lightheadedness, and blurred vision. It can also cause fainting (syncope).

  • Treatment usually involves lifestyle changes like standing up slowly, drinking plenty of fluids, and avoiding alcohol. In some cases, medication may be prescribed.

• Chronic Fatigue Syndrome (CFS): This is a complex disorder characterized by extreme fatigue that can't be explained by any underlying medical condition. The fatigue worsens with physical or mental activity, but doesn't improve with rest.

  • Treatment for CFS focuses on symptom relief. This can involve a combination of lifestyle changes, psychological therapy, and medication.

• Postural Orthostatic Tachycardia Syndrome (POTS): This is a condition that affects circulation (blood flow). It involves the autonomic nervous system and sympathetic nervous system. Symptoms can include lightheadedness, fainting, and rapid heartbeat.

  • Treatment usually involves a combination of lifestyle changes and medications.

• Anemia: This is a condition that develops when your blood lacks enough healthy red blood cells or hemoglobin. Hemoglobin is a main part of red blood cells and binds oxygen. If you have too few or abnormal red blood cells, or your hemoglobin is abnormal or low, the cells in your body will not get enough oxygen. Symptoms can include fatigue and weakness.

  • Treatment depends on the cause of the anemia, but may include dietary changes, supplements, and in severe cases, transfusions or surgery.

• Hypothyroidism: This is a condition in which your thyroid gland doesn't produce enough of certain crucial hormones. Hypothyroidism may not cause noticeable symptoms in the early stages. Over time, untreated hypothyroidism can cause a number of health problems, such as obesity, joint pain, infertility and heart disease. Symptoms can include fatigue, weakness, and depression.

  • Treatment usually involves daily use of the synthetic thyroid hormone levothyroxine.

Please remember that these are possibilities, not a definitive diagnosis. It's important to consult with a healthcare provider for an accurate diagnosis.

What you can do

1. Make an appointment with your healthcare provider to discuss your symptoms. They may want to perform some tests to help determine the cause of your symptoms.
2. Keep a symptom diary. Note when your symptoms occur, what you're doing at the time, and what you've eaten. This can help identify patterns and potential triggers.
3. Stay hydrated and try to maintain a balanced diet.
4. Try to stand up slowly. This can help reduce the lightheadedness and blurred vision.

What you should look out for

Seek immediate medical attention if:

• Your symptoms worsen or you develop new symptoms
• You faint or lose consciousness
• You experience chest pain or difficulty breathing
