Endocrine problems. Thyroid conditions such as parathyroid disease, adrenal insufficiency (Addison's disease), low blood sugar (hypoglycemia) and, in some cases, diabetes can trigger low blood pressure.

Blood loss: Blood loss during birth, or from injury or other medical problems can cause hypotension. Heart problems: A heart infection, abnormal heartbeats, or patent ductus arteriosis (PDA) may cause hypotension. Medicines: Infants born with high BP may be given medicines to lower the pressure.
