Symptoms

The presentation of PoTS is diverse reflecting the wide effects of autonomic dysfunction.

 

Many symptoms are similar to those seen in people diagnosed with Chronic Fatigue Syndrome, (Myalgic Encephalomyelitis) etc. Often it is the diversity of apparently unrelated symptoms defying a unifying diagnosis that prompts investigation for PoTS.

 

 

Common symptoms are:

 Lightheadedness

Fainting

Palpitations

Exercise intolerance

Fatigue and generalised weakness

Bloating after meals

Nausea

Shakiness

Anxiety

 

 

Less commonly:

 Brain fog

Difficulty concentrating

Memory problems

Sleep disturbance

Headache

Breathlessness

Diarrhoea

Constipation

Abdominal pain

Chest discomfort

Even less commonly:

 Bladder dysfunction

Sweating disturbance

Pupillary dysfunction

Blurred vision

 


 

PoTS symptoms often vary from day to day. They tend to be especially pronounced when upright. Heat, exercise and eating can exacerbate symptoms and they may be more troublesome around menstruation.
