There are many causes of hypotension, including nervous disorders due to lack of rest, excessive fatigue, and staying up late in some normal populations, which can cause hypotension. It can also be limited to some elderly and frail patients, or due to uncontrolled diet and insufficient provision of nutrients, leading to nutritional deficiencies and low blood volume causing hypotension. These hypotensions can be alleviated by adjusting lifestyle and supplementing nutrition. Hypotension is more commonly caused by certain diseases, such as infections, blood loss, heart failure, arrhythmias, and severe cardiomyopathy, which can lead to hypotension. This type of hypotension requires timely treatment and emergency intervention to save the patient's life.
