Subsequent hypertension is a high blood pressure caused by a clear cause, accounting for 5-10 per cent of all cases of hypertension. Unlike common primary hypertension, secondary hypertension are caused by other diseases or special physiological conditions. If the underlying causes of hypertension can be found and treated, blood pressure can often return to normal, so early detection and correct diagnosis are particularly important. Below, we have detailed information on the characteristics, causes, symptoms and treatment of secondary hypertension in plain and understandable language.
What’s secondary hypertension? In short, secondary hypertension are increased by a specific disease or physical abnormality. For example, kidney diseases, endocrine disorders or certain drugs can lead to increased blood pressure. High blood pressure of this type tends to develop more rapidly and at a higher level, often requiring a reduction in blood pressure through treatment of primary diseases. Unlike primary hypertension, secondary hypertension may occur suddenly at a certain age, with some unusual symptoms, so it can be traced back to the cause of the disease and can be cured.
Symptoms of subsequent hypertension are similar to those of primary hypertension, but may be more serious or may be accompanied by some unusual behaviour. The following are symptoms that may indicate secondary hypertension: sudden increase in blood pressure; rapid increase in blood pressure without apparent cause, usually exceeding 180/110 mmHg. Uncontrollable hypertension: Despite the use of a variety of depressive drugs, blood pressure is still difficult to reduce. High blood pressure for young patients: If young people (under 30 years of age) suddenly experience high blood pressure, especially without family history. Other symptoms: Appearance pain or urine anomaly: hints may have kidney problems. Sweat, heart attack, headache: may be related to endocrine anomalies. Muscle incompetence or convulsion: May be associated with electrolyte disorders.
1. Renal diseases 1. The kidney is an important organ for regulating blood pressure and any impairment or abnormality causes an increase in blood pressure: Chronic kidney disease (CKD): impairment of the kidney function causes sodium in the body and increases blood pressure. A narrow kidney artery: The narrow kidney artery leads to a decrease in kidney blood flow, irritating renal sterilisation and increasing blood pressure. Multiple kidneys: cysts oppress kidney tissue and can also cause hypertension. 2. Endocrine diseases Obsolete hormonal abnormalities resulting in increased blood pressure: adrenal neoplasm (chromosomal cytotums): excessive adrenalin and deetrenalin, resulting in an acceleration of the heart rate and high blood pressure. Prophyximate pyrosterone amplification: excessive scrutinized pyrosterone, resulting in sodium sodium retention and increased blood pressure. Kuchin syndrome: Too much cortex alcohol leads to more stress-sensitive blood vessels. Thyroid hyperactivity or decline: all influence blood pressure regulation. 3. Angiological diseases. Aorexic constriction: Innate aortic constriction increases the resistance of the heart to pump blood into the body, thus increasing blood pressure. 4. Drugs or substances Certain substances and chemicals cause secondary hypertension: Hormonal drugs: e.g., contraceptives or sugar-coated hormones. Inflammatory drugs (NSAIDs): Long-term use may cause blood pressure to rise. Illicit drugs: cocaine, etc. 5. High blood pressure associated with pregnancy The possibility of high blood pressure or pre-eclampsia during pregnancy is also a type of secondary hypertension.
(b) Heart damage: the left heart chamber is thick and even heart failure. In the brain: hypertension increases the risk of brain bleeding or brain infarction. Kidney failure: Long-term hypertension further exacerbates kidney damage. Retinasis: May cause loss of sight or blindness. Responsive hypertension progress faster and more harmful than primary hypertension.
Diagnosis of subsequent hypertension The diagnosis of secondary hypertensive hypertension requires a thorough examination to find potential causes: Blood and urine screening: examination of indicators such as kidney function, electrolyte, kidneys, and lysin. Visual examination: Renal ultrasound: assessment of kidney size, morphology. Renal artery: Check for constriction of kidney artery. CT or MRI: used to detect adrenal or thyroid tumours. Dynamic blood pressure monitoring: Record all-day blood pressure fluctuations to avoid “white coat hypertension”. Special examinations: hormonal level tests, load tests, etc., for the diagnosis of endocrine diseases.
The key to the treatment of re-emergence hypertension is to find and address the underlying causes: Renal patients need medication to control their condition to avoid further deterioration. Endocrine diseases: chromosomal cytotums, increase in primary formaldehyde, etc. can be surgically removed from pathological tissues. (a) High blood pressure associated with pregnancy: The need for medication under the guidance of an obstetrician to ensure the safety of the mother and the child. 2. Drug control, if primary diseases cannot be fully cured, may require the long-term use of pressure relief drugs such as: Beta receptor retardant: Reduced heart rate. Calcium route retardant: Relax the blood vessels and lower blood pressure. 3. Lifestyle adjustment. Even with secondary hypertension, a healthy lifestyle remains an important part of controlling the condition: low salt diet: daily salt intake is controlled at less than 5 grams. Stop drinking: Reduce cardiovascular stress. Moderate exercise: a minimum of 150 minutes per week for walking and swimming.
How to prevent secondary hypertension? Although many of the causes of secondary hypertension cannot be fully avoided, the following measures help to reduce risk: Avoiding substance abuse: Careful use of drugs that may affect blood pressure, such as contraceptives and hormones. Maintaining a healthy lifestyle: Healthy diets, routines and modest motion contribute to reducing the risk of hypertension.
Although only a small fraction of the cases of high blood pressure are summed up, early diagnosis and treatment are particularly important because of their clear causes and potential curable properties. If blood pressure is found to be abnormally high and difficult to control, the possibility of secondary high blood pressure should be monitored, prompt medical treatment and thorough examination. Healthy lifestyles not only work to control secondary hypertension but also improve overall cardiovascular health. Remember: high blood pressure is a “invisible killer,” but scientific control can make it stop threatening your life!
