Postural Orthostatic Tachycardia Syndrome (POTS) is a condition where the heart rate increases rapidly after standing up from a lying or sitting position, accompanied by lightheadedness, fainting, and other symptoms. The symptoms of POTS can vary from person to person and may include:

• Dizziness or lightheadedness, especially when standing up, during prolonged standing in one position or on long walks.
• Fainting or near fainting.
• Forgetfulness and trouble focusing (brain fog) .
• Heart palpitations or racing heart rate.
• Exhaustion/fatigue.
• Feeling nervous or anxious.
• Shakiness and excessive sweating.
• Shortness of breath (dyspnea) .
• Chest pain.
• Headaches.
• Feeling sick.
• Bloating.
• A pale face and purple discoloration of your hands and feet if they’re lower than the level of your heart.
• Disrupted sleep from chest pain, racing heart rate, and excessive sweating during sleep.

POTS can be caused by an imbalance in the autonomic nervous system, which controls involuntary body functions such as heart rate and blood pressure. It can develop suddenly or gradually over time and can be associated with other conditions such as diabetes, Lyme disease, or autoimmune disorders. While POTS isnt life-threatening, it can greatly interfere with daily living and tasks. The good news is that a variety of treatments and strategies can help improve symptoms[[3]](https://www.nhs.uk/co...
