Hypertension caused by primary aldosteronism can be diagnosed by clinical manifestations, laboratory tests and imaging tests. Specific need to hospitalization, improve the relevant examination to clarify.
1. Clinical symptoms: hypertension caused by primary aldosteronism not only has symptoms of dizziness and headache when the blood pressure is high, but also combines with symptoms such as weakness of limbs, thirst and excessive urination. Traditional antihypertensive drugs have poor therapeutic effect.
2. Laboratory tests: patients with primary aldosteronism are often accompanied by low blood potassium, i.e. hypokalemia. Increased urinary potassium, increased aldosterone concentration in the blood, and increased aldosterone/renin ratio in the blood.
3. Imaging: CT or MRI of the adrenal glands can help to detect tumors of the adrenal glands.
4. Saline loading test or captopril test is used as a confirmatory test for primary aldosteronism.
Precautions: If you have hypertension, you need to actively consult the hospital to find the cause of hypertension and target the diagnosis and treatment.
