Symptoms of POTS are known to overlap with symptoms of other dysautonomia syndromes such as abdominal cramps, bloating and diarrhea. Additional overlapping symptoms are constipation, aches and pains, and extreme fatigue, says About.com. POTS is a type of dysautonomia characterized by an inappropriate elevation in heart rate when the patient stands up. A drop in blood pressure often accompanies the change in heart rate. Episodes of passing out affect up to 40 percent of POTS patients.

This condition is most common in typically healthy young people aged 14 to 45. Women are at a higher risk of developing POTS than men, reports About.com. Some families seem to have a disposition toward this condition. POTS develops when the autonomic nervous system is out of balance. Certain syndromes such as fibromyalgia, chronic fatigue syndrome, irritable bowel syndrome and inappropriate sinus tachycardia are linked to dysautonomia.

The underlying cause of various types of dysautonomia is unknown, as of 2015. POTS commonly manifests suddenly and is known to follow acute infections, trauma, exposure to toxins and severe emotional distress, states About.com.
