Are you aware of Sodium Bicarbonate, which is used in medical tests?
Table of Contents ▾

Have you ever had to undergo a special test, such as an endoscopy or an X-ray of the stomach, due to a condition such as stomach pain or gastritis? In such cases, doctors use various things to make the inside of the stomach clearly visible before the test. One such medicine is sodium bicarbonate. But this is not the baking soda we use for food, it is something that is given for a different medical need. Let's talk about this in detail.

What is sodium bicarbonate and why is it given?

Simply put, this is a medicine that comes in the form of granules. A doctor or health professional gives it to you to drink. When you drink this, it creates gas in your stomach and makes your stomach swell a little. Then the walls of the stomach are stretched, and when you take an X-ray or other scan, the doctor can see the structures inside the stomach very clearly in those images.

The most important thing: This is a medication that is only given under the supervision of a doctor, in a hospital or clinic. It is not something that can be bought at a pharmacy and used at home.

Things you need to tell your doctor before taking this medicine

Before this test, your doctor will ask you some questions. However, if you have any of the following conditions, you should definitely tell your doctor.

  • Allergies: If you have an allergic reaction to sodium bicarbonate or any other medicine, food, or preservatives, you should tell your doctor.
  • Throat, stomach, or intestinal problems: Tell your doctor if you have difficulty swallowing, a blockage in your throat, stomach, or intestines, a perforation, or if you have recently had surgery related to this.
  • Low-sodium diet: If your doctor has told you to follow a low-salt (low-sodium) diet, you should mention that as well, as this medication also contains sodium.
  • Pregnancy or breastfeeding: It is essential to inform your doctor if you are pregnant, trying to become pregnant, or breastfeeding.

How to use this medicine and is it suitable for children?

This is not a medicine that you can take home and take every day. It is only used in a hospital or clinic. It is given to you by a healthcare professional (doctor or nurse) there.

This medication is not generally approved for use in children. Therefore, if your child needs to have this type of test, talk to your pediatrician about it to determine the best course of action.

What do you do if you accidentally take too much?

This is a hospital-based treatment, so the chances of this happening are low. However, if you think you may have overdosed on this medicine, go to the nearest hospital Emergency Department (ETU) immediately. Alternatively, you can call the National Poisons Information Centre at the Colombo National Hospital for advice.

Interactions with other medications

Some medications can cause problems when taken with sodium bicarbonate. Therefore, you should tell your doctor about all the medications you are taking, including prescription medications, over-the-counter medications, herbal remedies, vitamins, and supplements. Also, tell your doctor if you smoke or drink alcohol.

FAQ

Evidence-based clinical answers to common patient questions

💬 What is Sodium Bicarbonate (Baking Soda) given in hospitals?

Although this is usually 'baking soda' used in cooking, this sodium bicarbonate (tablets/injections) given by pharmacies in hospitals is an extremely important and powerful life-saving medicine! It is used when the liver/kidneys have failed and the 'acidity/acidity (Acidosis)' in the blood or urine has become unbearable, to eliminate that acidity and save the patient's life.

💬 How to reduce acidosis in the body?

Sodium bicarbonate (NaHCO3) is an alkaline chemical. When your kidneys fail, acid builds up in your blood, causing metabolic acidosis. When this medicine enters your blood or stomach, it reacts with the excess acid (H+ ions) and immediately turns into carbon dioxide and water. Within minutes, the acid in your body will be gone and the patient will regain consciousness.

💬 What are the side effects of continuing to take this medicine (Sodium Bicarbonate)?

The biggest problem is that when this is dissolved with acids, it produces 'gas (carbon dioxide)'. Therefore, those who take these (especially for heartburn/as antacids) experience bloating, gas and weakness, and possibly even an intestinal/stomach explosion. Also, since it contains a lot of 'sodium/salt', people with kidney/heart problems may experience severe swelling/edema in their legs and increased blood pressure!
