4. Postural Orthostatic Tachycardia Syndrome
Postural orthostatic tachycardia syndrome is a condition that affects up to around 3 million people in America. Only around 20% of people with the condition are male, and it is more likely to affect people that have an existing autoimmune condition like multiple sclerosis.
Typical symptoms of the condition include a fast heart rate, fainting, and lightheadedness. Patients will also often be short of breath, and pains in the chest are also common. Shaking is another potential symptom and patients will also sometimes have an upset stomach. Patients can also become overly sensitive to hot and/or cold, and they can also tire from exercise more easily than usual.
