Are you suffering from hypertension? Do you consider yourself obese? Are you planning to decrease your weight and want to know “Can weight loss reduce blood pressure?” Or are you just a medical student learning about it? This article is helpful for all of you.
According to a research paper, there are almost 500 million obese people in the world. This number is increasing rapidly in developed countries.
Many studies have confirmed that obesity and overweight increases the risks of cardiovascular diseases, stroke, and some cancers.
It is also a major factor in causing hypertension. Let me break it to you step by step how weight loss and blood pressure are related.
What is Hypertension?
It is defined as systolic blood pressure more than 140 mm Hg and diastolic blood pressure more than 90 mm Hg. The normal blood pressure is 120 mm Hg by 80 mm Hg.
Hypertension is called a silent killer because the majority of the patients are not aware of it. If it gets diagnosed at an early stage, it can be managed by anti-hypertensive drugs.
How Obesity causes Hypertension?
Obese people have increased lipids (fatty acids) in their blood. It is believed that this reduces the action of insulin on the cells. Which leads to hyperglycemia (increased sugar in the blood) as well as increased blood pressure. This is the reason why type 2 diabetics suffer from hypertension.
One other reason is, the increased lipids in the blood is responsible for atherosclerosis or narrowing of the blood vessels.
This not only causes increased blood pressure but is the main culprit behind cardiovascular diseases.
The exact cause is still unknown. Weight loss might not directly reduce blood pressure instead it could be the changed diet that is causing it.
How Weight Loss is Effective in Hypertension?
“Can weight loss reduce blood pressure?” As you know now how obesity and hypertension are related. You can easily deduce how weight loss is effective in reducing blood pressure.
According to this research paper, they concluded that one kg loss of body weight causes at least one mm Hg reduction in blood pressure.
There are many other such studies, with little different values, that all concluded that weight loss is highly effective in reducing blood pressure.
