[22F] Experiencing fast heart rate, nausea, and other symptoms

What might be happening

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

• Hyperthyroidism: This condition occurs when your thyroid gland produces too much of the hormone thyroxine. Symptoms can include increased heart rate, tremors, changes in menstrual patterns, and heat intolerance. Your family history of thyroid problems and your symptoms of heat intolerance, weight gain, and changes in bowel movements could suggest this condition.

  • Diagnosis typically involves blood tests to measure your levels of thyroid-stimulating hormone (TSH) and thyroxine. Treatment can include medication, radioactive iodine, or surgery.

• Panic Disorder: This is an anxiety disorder characterized by recurrent unexpected panic attacks. Panic attacks are sudden periods of intense fear that may include palpitations, sweating, and shaking. Your history of anxiety and OCD, along with your symptoms of a fast heart rate, trembling, and feeling like you're about to throw up, could suggest this condition.

  • Diagnosis is typically made based on your symptoms and medical history. Treatment can include psychotherapy, medication, or both.

• Premenstrual Dysphoric Disorder (PMDD): This is a severe form of premenstrual syndrome that includes physical and behavioral symptoms that usually resolve with the onset of menstruation. Your symptoms of irregular periods, fatigue, and a general sick feeling could suggest this condition.

  • Diagnosis is typically made based on your symptoms and their timing in relation to your menstrual cycle. Treatment can include lifestyle changes, medication, or both.

Please remember that these are just possibilities based on the information you've provided, and they are not a definitive diagnosis. Only a healthcare provider can provide a formal diagnosis.
