The salt also known as sodium chloride is a compound composed of 40% sodium and 60% chloride. Both are electrolytes which hold the most important function in health. Electrolytes are atoms with an electric charge in body fluids. Its influence in the work of the human body are several.

Sodium, for example, acts in muscle contraction, benefits of nerves, and controls volume and blood pressure. Sodium deficiency due to sweating or loss of fluid can cause muscle cramps. In addition, chloride helps monitor fluid equilibrium in cells so that the volume and pressure of the blood are still constant.

Is Salt Really Causing High Blood Pressure?

So if these two minerals are actually the most important, why do many say if salt causes hypertension or high blood pressure?

Connections to salt and hypertension 


About 95% of hypertensive people are diagnosed with primary hypertension, which is when the trigger for this condition is not found. Moderate secondary hypertension is hypertension caused by other diseases and can still be cured.

In primary hypertension, there are several aspects mentioned that can increase the risk of hypertension, including salt consumption. Yes, many say if salt causes hypertension. Even though it's actually not that simple.

Disposal of used fluid on the body by the kidneys depends on the balance of sodium and potassium to bind water and deliver it to the bladder. Generally salt consumption will cause sodium and potassium equilibrium damage, so that the kidneys work hard. What then goes on is retention (accumulation) of fluid coupled with the increase of blood pressure.

Generally salt consumption contributes to the pressure that weakens the arterial wall. This depressed artery will thicken and become narrower, until the blood pressure also rises. Next, the arteries will break or be blocked.

The organ organs connected to the damaged artery then lack oxygen. Lack of oxygen can cause damage to organs. If this happens in the coronary arteries that supply the heart, you can have a heart attack.

Maybe you are sensitive to salt 


Hypertension is a health condition that is influenced by genetic aspects (heredity) and lifestyle. Although research has shown that salt is one of the most important aspects of hypertension in terms of lifestyle, the risk is different for each person.

Some experts find that some people might be fine even though the eating scheme is high in salt. However, there are also those who experience high blood pressure or flatulence if generally salt. The situation that is intended to be sensitive to salt can be faced by anyone, either having hypertension or not.

Sensitivity to salt is a condition inherited from the family. People with this condition need to monitor their salt consumption with jelly. Not only aspects of heredity, there are some things that ensure how your blood pressure reacts to salt.


  • Type sex: Women experience more sensitivity to salt than men.
  • Age: People over 45 years may be more sensitive to salt.
  • Obesity.
  • Have medical conditions: Hypertension, diabetes, and acute kidney disease can increase your risk of being sensitive to salt.


According to the American Heart Association, more than 50% of people are sensitive to salt. In fact, 1 in 4 people with normal blood pressure are actually sensitive to salt and at risk of natural hypertension because the current eating scheme is high in salt.

Are only salt suspects? 


We cannot just accuse salt of causing hypertension. According to research in the Open Heart journal, consuming excessive sugar can also make blood pressure rise. This is because generally the body's sugar will increase insulin content. From there, high insulin will activate the sympathetic nerve scheme. The body will respond by increasing the heart rate and increasing blood pressure. In addition, the receptors that work to control the blood pressure content are also impaired.

The high-sugar eating scheme, even if only taken a few weeks, is reported to have a rather large effect on blood pressure. Even the effects are staying bigger than the high-salt eating scheme. In separate research, people who drank 700 ml of sweet drinks showed the addition of blood pressure in just a few moments afterwards.

The key is balanced consumption


Although limiting salt consumption is good, lack of salt can also be dangerous. So, you do not need to abstain from salt really because fear of salt causes hypertension. That is why it is recommended to reduce the most important salt of people who are sensitive to salt.

The best step to start limiting salt is to reduce consuming instant food in the package. The problem around 77% of daily sodium is generally obtained from packaged foods (frozen meat, processed cooking spices, and canned food).

Reduce package food will move you to consume foods high in vitamins, minerals, fiber, and other important nutrients. Plus if it is balanced with the consumption of magnesium and potassium that are balanced, you do not need to really make a headache about what salt causes high blood pressure.
