Hi, Let me inform you that low blood pressure cannot be itself happening, and it is the medical emergency if ever happens due to loss of fluid from the body even blood that may cause the hypotension (Law blood pressure). Second, it can be due to starvation, low water intake. Third, it can be due to vasovagal shock (most common condition is seeing the bleeding condition). All of the mentioned conditions are medical emergencies that demand immediate medical attention. You have not mentioned any symptoms here, as long as the given symptoms that you described here may demand cardiac evaluation and other vascular condition. Till then drink more water, stay away from anxiety and depression, most of the time it could be some functional condition responsible for the symptoms that you have. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Akhtarhusain, General & Family Physician
