Hypertension always harms our health quietly, and early patients have no obvious discomfort, so hypertension is called the "invisible killer" of human health. However, no matter how cunning the enemy is, he will give away the clues. Small details such as headache and tinnitus are probably the body calling the police. Mastering these dangerous signals and monitoring blood pressure in time are helpful to control the disease.

Dizziness. This is the most common symptom in patients with hypertension. Possible reasons: 1. Blood pressure drops too low or long-term hypertension leads to insufficient blood supply to the brain and dizziness. Blood pressure fluctuation can cause vasoinhibitory vertigo, which is more common in female patients and may occur when suddenly squatting or standing up. 2. Hypertension can enhance the pulsatility of cerebral arteries, and then impact and oscillate brain tissue, causing dizziness.

Insomnia, rising blood pressure will lead to dysfunction of cerebral cortex and autonomic nervous system, and indirectly cause insomnia symptoms such as difficulty in falling asleep, easy to wake up, unreliable sleep, easy to have nightmares and easy to wake up. When blood pressure rises, autonomic nervous activity increases, which will lead to rapid heartbeat, shortness of breath, and myriad thoughts, which will also lead to difficulty in falling asleep.

Tinnitus. Hypertension can lead to arteriosclerosis and inner ear spasm, and the function of auditory nerve is degraded due to insufficient blood supply. Tinnitus caused by hypertension is mainly characterized by intermittent buzzing in the ears, like a low voice when a waterwheel rotates. Its characteristic is that tinnitus in both ears is intermittent and lasts for a long time

Headache. One of the common symptoms of hypertension can be manifested as persistent dull pain or pulsating pain. When blood pressure is too high, viscera and arterioles of limbs contract obviously. Due to the poor contraction of cerebral vessels, the blood flowing into the brain increases correspondingly, causing congestion and dilation of arteries, causing headaches and sometimes even nausea and vomiting. Most of them are caused by the sudden increase of blood pressure, which may be a signal to turn into malignant hypertension.

Numbness of limbs. When blood pressure fluctuates or rises, the arterioles of the whole body spasm, leading to vasomotor dysfunction or arteriosclerosis, causing local blood supply deficiency in limbs and numbness in limbs, especially when long-term hypertension is not well controlled.
