Next, let us introduce some symptoms of low blood pressure. Actually, low blood pressure is divided into physiological and pathological low blood pressure. Generally speaking, physiological low blood pressure is asymptomatic, while pathological low blood pressure might have six major types of symptoms: The first type is fatigue and weakness, especially in the morning. Patients may feel listless and weak in their limbs which can improve after a nap or rest, but the fatigue may return in the afternoon or evening; The second type of symptoms includes headaches and dizziness. Among patients with low blood pressure, headaches are a common complaint, often occurring after intense mental activity or physical exertion. The nature and severity of headaches can vary, often manifesting as dull pain in the temporal or occipital region, but can also be intense pulsating pain or numb pain. Dizziness can vary in severity; mild cases involve blackout vision and vertigo, while severe cases can lead to fainting spells and even collapse, often occurring during sudden changes in body position, or when moving from a squatting to a standing position; The third type of symptoms involves chest pain or discomfort in the cardiac area, where patients with low blood pressure often experience such discomfort; The fourth type involves neurological dysfunctions, which can manifest as lethargy, reduced memory, sleep disturbances or insomnia, and severe cases may show signs of autonomic dysfunction. Symptoms might include pale skin, mild cyanosis, fluctuations between feeling cold and hot, sensations of ants crawling, or numbness in hands and feet; The fifth type of symptoms is reduced endocrine function, primarily shown as insufficient levels of substances like adrenaline and noradrenaline. Some patients may exhibit reduced blood sugar levels or decreased sexual function; The sixth type of symptoms includes poor appetite, abdominal discomfort, indigestion, or increased red blood cell count, decreased white blood cell count, reduced immunity, making infections more likely, etc.
