The hot summer is the high season for hypertension, which can rise with a little inattention. Hypertension is asymptomatic or mildly symptomatic in its early stages, which is not easily detected and can be easily missed. Mild headache, head swelling, dizziness or neck swelling, sometimes distraction, insomnia, lack of concentration, memory loss, etc. may be the early symptoms of hypertension, let’s take a look together. 1, headache The headache can be caused by a variety of reasons, but people rarely think that this is also the onset of hypertension, so it is easy to ignore. It is important to note that the headache induced by hypertension has its own characteristics, which are generally persistent dull pain or throbbing distension, or even severe pain like frying. It often occurs in the morning when waking up, and gradually decreases after getting up and moving and eating. The pain is mostly in the temples and the back of the head on both sides of the forehead, and is accompanied by nausea and vomiting. If you have frequent and severe headaches and nausea and vomiting at the same time, it may be a sign of transformation to malignant hypertension. 2, vertigo Vertigo is also a symptom of hypertension that is easy to ignore, and we should be alert to pay attention to the identification. Anyone who has high blood pressure will respond that they have experienced dizziness. The reason for this may be that blood pressure has been lowered too low or chronic hypertension has led to insufficient blood supply to the brain, producing dizziness. Blood pressure fluctuations can cause vasodepressive dizziness, which occurs more often in female patients and may come on when they suddenly squat or get up. Hypertension can enhance the pulsating sensation of cerebral arteries, which in turn creates shocks and oscillations in brain tissue, causing dizziness. 3. Insomnia Patients with hypertension often have trouble sleeping after the onset of the disease, and the symptoms are difficult to lift. Continuously elevated blood pressure can lead to dysfunction of the cerebral cortex and autonomic nerves, thus indirectly causing insomnia symptoms such as difficulty in falling asleep, easy to wake up, unstable sleep, easy to have nightmares, and easy to wake up. Elevated blood pressure and increased autonomic activity can cause rapid heartbeat, shortness of breath and racing thoughts, which can also lead to difficulty falling asleep. 4. Tinnitus Tinnitus is especially easy to be overlooked by everyone, and even if it produces distress, patients will belittle timely diagnosis and treatment. Hypertension can lead to arteriosclerosis and spasm in the inner ear, causing degeneration of the auditory nerve function due to insufficient blood supply. The main manifestation of tinnitus caused by hypertension is an intermittent buzzing sound in the ears, a low sound like a waterwheel coming and going. It is characterized by intermittent tinnitus in both ears, which lasts for a long time. 5. Palpitations and shortness of breath Hypertension can lead to cardiac hypertrophy, heart enlargement, myocardial infarction, and cardiac insufficiency. These are all symptoms that lead to palpitations and shortness of breath. If this happens, it also needs to be noticed. 6, numbness in the limbs Commonly numbness in the fingers and toes or skin such as an anthroposophic sensation and inflexible fingers. Numbness may also occur in other parts of the body, and may also feel abnormal, or even hemiplegia. If this symptom occurs, be sure to check carefully if you are suffering from hypertension.
