[21F] Experiencing dizziness, nausea, irritability, and palpitations

Patient Description

A 21-year-old female has been experiencing a range of symptoms that include dizziness, nausea, irritability, and palpitations for several years. The dizziness, described as a combination of spinning and lightheadedness, occurs regardless of the speed at which she stands up, sometimes leading to temporary vision loss. This symptom has been persistent for years, with a severity rating of 7 out of 10. Closing her eyes and standing still sometimes alleviates the dizziness. Nausea has been a more recent concern, occurring randomly throughout the day for a couple of weeks, with a severity rating of 8 out of 10. It sometimes leads to vomiting, and high sugar levels appear to worsen the condition. The patient has also noted an increase in irritability, affecting her interactions with others. Palpitations, described as racing or pounding of the heart, especially upon standing or during exercise, have been occurring for a few years. The patient has a medical history of type 1 diabetes, overactive thyroid, depression, anxiety, and PTSD, diagnosed between 2008 and 2022. She is currently on Synthroid (175mg), Lisinopril (2.5mg), insulin (as needed), Zoloft (175mg), vitamin D (10,000 IU), and hydroxyzine (75mg), and has a known allergy to prazosin.

What might be happening

Based on the symptoms you've described, a few possible conditions could be contributing to your symptoms:

  • 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 a rapid increase in heartbeat rate with standing. The fact that you experience dizziness and palpitations when standing up could be indicative of this condition.

    • Diagnostic tests for POTS typically involve a tilt table test or a standing test. Treatment often involves lifestyle changes and sometimes medication.

  • Thyroid disorders: Given your history of an overactive thyroid, it's possible that your thyroid hormone levels are not well controlled, which could be contributing to your symptoms. Both hyperthyroidism and hypothyroidism can cause symptoms like fatigue, irritability, and heart palpitations.

    • Regular monitoring of thyroid hormone levels and adjusting your medication as necessary is the typical approach to managing thyroid disorders.

  • Anxiety and Depression: These mental health conditions can cause a variety of physical symptoms, including nausea, irritability, and palpitations. Given your history of both conditions, it's possible that they are contributing to your current symptoms.

    • Treatment typically involves a combination of medication, therapy, and lifestyle changes.

What you can do

  1. Consult with your healthcare provider: Given the range and severity of your symptoms, it's important to discuss these with your healthcare provider. They can help determine the cause and appropriate treatment.

  2. Monitor your symptoms: Keep a log of when your symptoms occur, their severity, and any potential triggers. This can help your healthcare provider in diagnosing and treating your condition.

  3. Stay hydrated and maintain a balanced diet: Dehydration and poor nutrition can worsen many of the symptoms you're experiencing.

  4. Practice good sleep hygiene: Ensure you are getting enough sleep and maintaining a consistent sleep schedule. Fatigue can exacerbate many of the symptoms you're experiencing.

What you should look out for

Seek immediate medical attention if you experience any of the following:

  • Severe chest pain
  • Difficulty breathing
  • Fainting
  • Severe abdominal pain
  • Symptoms that are rapidly worsening or are severe

Remember, while I strive to provide accurate and helpful health information, I'm not a doctor. Always consult with a healthcare provider for a formal diagnosis and treatment.
