[39F] Experiencing severe fatigue, blurred vision, and other symptoms

What might be happening

Based on the information provided, possible diagnoses include:

• Hypothyroidism: This is a condition where the thyroid gland does not produce enough thyroid hormones. Given your history of Hashimoto's thyroiditis and thyroidectomy, this is a strong possibility. Symptoms can include fatigue, weight gain or difficulty losing weight, hair loss, and feeling cold.

  • Treatment typically involves taking a synthetic thyroid hormone, such as levothyroxine, which you are already taking. Your dosage may need to be adjusted.

• Anemia: This is a condition where you lack enough healthy red blood cells to carry adequate oxygen to your body's tissues. Symptoms can include fatigue, weakness, pale or yellowish skin, irregular heartbeats, shortness of breath, dizziness or lightheadedness, and chest pain.

  • Treatment depends on the cause and severity of the condition but may include dietary changes, supplements, medications, or procedures to increase the number of red blood cells.

• Chronic Fatigue Syndrome (CFS): This is a complicated 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. Other symptoms can include loss of memory or concentration, sore throat, enlarged lymph nodes in your neck or armpits, unexplained muscle or joint pain, headaches, and unrefreshing sleep.

  • Treatment focuses on symptom relief.

• Fibromyalgia: This is a disorder characterized by widespread musculoskeletal pain accompanied by fatigue, sleep, memory, and mood issues. It's often considered a rheumatic condition, a condition that impairs the joints and/or soft tissues and causes chronic pain.

  • Treatment often involves a team approach, using healthcare providers from different fields. Medications, cognitive behavioral therapies, and gentle exercise are the most common treatments.

• Vitamin B12 deficiency: This can cause fatigue, weakness, constipation, loss of appetite, weight loss, and megaloblastic anemia. Nerve problems, such as numbness and tingling in the hands and feet, can also occur.

  • Treatment involves taking B12 supplements or getting B12 injections.

What you can do

Please consult a healthcare provider as soon as possible. They can order tests to confirm a diagnosis and start you on the appropriate treatment. In the meantime, try to maintain a balanced diet, stay hydrated, and get plenty of rest.

What you should look out for

Please seek immediate medical attention if you experience severe chest pain, difficulty breathing, severe headache, sudden vision changes, or if your symptoms significantly worsen.
