Depends on BP how lo: Fatigue is common in POTS (postural orthostatic tachycardia syndrome) for 2 reasons: 1) if ur BP is low, then ur brain doesn't get enough blood flow, & as a result u feel tired. 2) the causes of POTS isn't fully known, but some suspect it happens because of a virus or inflammatory reaction. Virus infections (like the cold, flu) cause u 2 b tired by their nature, & ur immune system takes up energy.
