Treatments for postural tachycardia syndrome, or POTS, can include orthostatic exercise, medication therapy, increased water intake and salt or fludrocortisones, according to the Rare Clinical Disease Research Network. More than one of these treatments can be used together, and treatment efficacy can vary greatly from patient to patient.
POTS can be detected by various symptoms. These symptoms can include lightheadedness, palpitations, changes in vision, pain or throbbing in the head, neck pain, difficulty concentrating, fatigue, weakness, fainting, nausea, chest pain or shortness of breath. These symptoms are especially indicative of POTS if they occur while the patient is standing or otherwise upright and at rest.
The disorder is most commonly diagnosed in women less than the age of 35. However, the cause remains unknown. Diagnosis is also challenging because the symptoms produced by POTS are similar to the symptoms produced by other common disorders. However, medical professionals can make a correct diagnosis by testing the patient's blood pressure while lying, sitting and standing, either immediately after sitting or at particular time intervals. To confirm the diagnosis, a head upright tilt table test can be performed.
Most patients with POTS will experience mild symptoms for a few weeks or months, and these symptoms can improve. However, some patients experience more serious symptoms and suffer for a longer period of time without improvement.
