[24M] Experiencing lightheadedness, chest pressure, and near-fainting episodes

What might be happening

Based on the information you've provided, possible diagnoses include:

• Panic Disorder or Anxiety Disorder: These conditions can cause symptoms such as lightheadedness, chest pressure, palpitations, sweating, nausea, and vomiting. They can also cause a sense of impending doom or feeling like you're about to faint. Anxiety can also lead to fatigue and decreased physical performance.

  • Treatment typically involves cognitive behavioral therapy and/or medication.

• Cardiovascular Conditions: Given your symptoms of chest pressure, lightheadedness, and shortness of breath, conditions such as heart disease or arrhythmias could be a possibility. These conditions can cause decreased blood flow to the brain, leading to lightheadedness and fainting.

  • Treatment typically involves lifestyle changes, medication, and sometimes surgery.

• Postural Orthostatic Tachycardia Syndrome (POTS): This is a condition that affects circulation and can cause lightheadedness and fainting, especially upon standing. It can also cause palpitations, fatigue, and exercise intolerance.

  • Treatment typically involves lifestyle changes and medication.

• Vasovagal Syncope: This is a common cause of fainting, often triggered by certain stimuli such as standing for long periods, heat exposure, or emotional distress. Symptoms can include lightheadedness, nausea, and sweating.

  • Treatment typically involves avoiding triggers and sometimes medication.

What you can do

While waiting for your appointment with a healthcare professional, here are some things you can do:

1. Try to stay hydrated and maintain a balanced diet. Dehydration and low blood sugar can contribute to lightheadedness.
2. If you feel lightheaded, lie down or sit down right away to prevent fainting and potential injury.
3. Practice deep breathing exercises and other relaxation techniques to help manage your anxiety.
4. Avoid alcohol and caffeine, as these can trigger or worsen your symptoms.
5. Keep a symptom diary to track when your symptoms occur, what you're doing when they occur, and what helps to alleviate them. This can be useful information for your healthcare provider.

What you should look out for

Please seek immediate medical attention if:

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