When one uses or loses more fluid than they take, they may suffer from dehydration. One is said to be suffering from dehydration when they lack enough water or fluid in their body. It can occur to just anyone regardless of age; however, children and ground adults tend to be more affected by dehydration.

Dehydration may also occur due to excessive vomiting and diarrhea in young children, while in adults, it may be caused by infections that affect the bladder and lungs. Another cause of dehydration can be the failure to drink enough water, more so in the hot weather or exercising. Dehydration has more effects on the human body some which include;


  • Heart complication; failure to drink enough fluid, especially when working on manual tasks or exercising, may result in heart cramps, heat exhaustion, and heatstroke.
  • Seizures; lack of fluid in the body may result in electrolytes imbalance. These electrolytes, such as potassium, carry signals from cell to cell. When imbalanced, they may multifunction and send mixed up signals leading to muscle contractions and unconsciousness.
  • Kidney complications; excessive fluid loss may result in kidney stones, urinary infections, and kidney failure.
  • Low blood pressure; lack of enough water or fluid leads to low blood volume and following a fall in blood pressure and oxygen levels.

In cases of low blood pressure due to dehydration, intravenous fluid has been known to increase the levels.


Low blood pressure may be deemed harmless in some cases. However, low blood pressure than the expected level of 90/60 mm Hg or hypertension may pose more problems such as fainting, dizziness, and other life-threatening complications. Other symptoms may include;

  • General body weakness
  • Confusion
  • A sick feeling
  • Blurry vision

If you endure either of the stated signs, it would be best to seek help and get checked by a doctor or medical practitioner. There are various forms of medication threat taken by patients to increase their blood pressure. Recent studies reveal that intravenous therapy (IV) is an effective treatment for hypertension during dialysis for dehydration patients. There are two types of IV treatments: IV drip and IV push, and the duration of each treatment depends on the amount of fluids administered. In treating hypertension, the treatment is preferred as it allows for over 90% of vitamin absorption in the body.


In IV drip treatment, it is infused into the bloodstream through a plastic tube (catheter) inserted into one of the patient’s veins using a needle. Once the catheter is inserted into the vein, the needle is then removed. The fluid is a combination of saline solution, electrolytes, and vitamins. The composition is used to address various health needs. The IV line is attached to a bag hung above the patient’s head containing a saline solution that contains Sodium Chloride and water to hydrate the patient’s body while facilitating the absorption of medication and vitamins. The fluid flows through gravity, and 250–1000ml fluids are injected every 45-60 minutes.


Once a catheter I inserted into the vein, and IV push is administered with 30-60 ml of fluids every 15-20 minutes. A specialist often supervises this procedure. The treatment may depend on some factors such as age and the type of hypertension.

Why choose IV Hydration

There are other modes like oral treatment that can be used to increase a patient’s blood pressure. However, due to factors like age, IV hydration is more effective and the preferred option. For oral treatment, it has to go through the digestive system first for metabolism before it can progress to the circulation system, meaning that it takes longer for the medication to take effect. As mentioned, factors such as age, illness, stress, and mal-absorption may influence oral treatment absorption.

With IV drip, 90-100% of the vitamins are absorbed as they are administered into the patients’ bloodstream, and this way, the patient’s body cells use up the vitamins and medication much faster. The IV hydration is ideal for patients who experience nausea or some illness due to difficulties digesting mediation and fluids and mal-absorption issues.
