Hypertension in Children and its Causes: Understanding the Risks

Hypertension, commonly known as high blood pressure, is a severe health condition that affects individuals of all ages. However, the incidence of hypertension in children is increasing alarmingly. According to recent studies, approximately 3.5% of children in the United States have hypertension, which is on the rise. This article aims to shed light on the causes of hypertension in children and the potential risks associated with the condition.

Causes of Hypertension in Children

Several factors can contribute to hypertension in children, including:

  1. Obesity – Childhood obesity is a significant risk factor for hypertension. Excess body weight puts extra pressure on the heart and blood vessels, which can cause blood pressure to rise.
  2. Genetics – Hypertension can run in families. Children with a family history of high blood pressure are likelier to develop the condition.
  3. Chronic kidney disease – Children with chronic kidney disease are at an increased risk of developing hypertension. This is because the kidneys play a vital role in regulating blood pressure, which can arise when not functioning correctly.
  4. Sleep apnea – Sleep apnea is a condition in which a person’s breathing is interrupted during sleep. Children with sleep apnea are at an increased risk of developing hypertension.
  5. Medications – Certain medications, such as steroids and nonsteroidal anti-inflammatory drugs (NSAIDs), can cause hypertension in some children.

Potential Risks of Hypertension in Children

Hypertension in children can lead to several potential risks, including:

  1. Cardiovascular disease – High blood pressure can damage the blood vessels and increase the risk of cardiovascular disease later in life.
  2. Kidney disease – Hypertension can cause damage to the kidneys and increase the risk of kidney disease.
  3. Vision problems – High blood pressure can damage the blood vessels in the eyes, which can lead to vision problems.
  4. Cognitive problems – Hypertension can affect cognitive function in children, including attention span, memory, and learning ability.
  5. Stroke – In rare cases, hypertension in children can lead to a stroke.


Q: How is hypertension in children diagnosed? A: Hypertension in children is diagnosed by measuring blood pressure at least three times on different occasions. The child’s blood pressure readings will be compared to age, sex, and height-specific norms.

Q: How is hypertension in children treated? A: Treatment for hypertension in children may include lifestyle changes, such as diet, exercise, and medication.

Q: Can hypertension in children be prevented? A: Hypertension in children can be prevented by maintaining a healthy weight, eating a healthy diet, exercising regularly, and managing stress.


Hypertension in children is a serious health condition that can lead to several potential risks. Understanding the causes of hypertension in children is vital for preventing and managing the condition. By maintaining a healthy lifestyle and seeking medical care when necessary, parents can help their children reduce the risks associated with hypertension.
