Important Considerations Before and After an Ultrasound

If you have questions about ultrasound and its procedure, you’ve come to the right place.

In this article, we will explore the various aspects of ultrasound, including why it is done on an empty stomach and the precautions to take before and after the procedure.

Ultrasound is a remarkable medical technique that utilizes high-frequency sound waves to generate images of the internal organs.

It is commonly used to detect diseases of the heart, kidneys, and liver, and is particularly vital for monitoring fetal development in pregnant women.

Let’s delve into the details provided by Dr. Sanjay Singhvi, a Radiologist at Singhvi Fordy Ultrasound in Kanpur, to ensure a smooth ultrasound experience.

Understanding Ultrasound:

What it is and Why it is Ultrasound is a non-invasive procedure that employs high-frequency waves to visualize organs, vessels, and tissues within the body.

This advanced technique allows for the diagnosis of various conditions without causing any discomfort to the patient.

By emitting sound waves and capturing the resulting echoes, ultrasound can create detailed scans of the body’s internal structures.

It is also known as sonography and encompasses three primary types: external, internal, and endoscopic ultrasound.

Types of Ultrasound

Ultrasound encompasses three main types, each serving a unique purpose:


This type of ultrasound examines the heart and helps identify any cardiac abnormalities.

3D Ultrasound:

It provides a three-dimensional representation of the internal body structures.

4D Ultrasound:

This form of ultrasound displays moving three-dimensional images, offering additional insights into the body’s dynamics.

Importance of Ultrasound

Ultrasound plays a crucial role in several medical scenarios, including:

Pregnancy Monitoring:

Ultrasound is essential for monitoring fetal development, ensuring the healthy growth of organs and tissues.

Soft Tissue Injuries:

It aids in locating injuries to soft tissues, such as muscles, which can result in pain, bruising, swelling, and loss of function.

Organ Examination:

Ultrasound assists in examining and diagnosing conditions affecting organs like the kidneys, bladder, gall bladder, and testicles.

Vein Localization:

When doctors face difficulty locating veins in patients, ultrasound is used to facilitate successful treatment.

Heart Health Assessment:

Ultrasound helps measure the amount of blood in the heart, providing valuable information for heart-related conditions.

Precautions Before Undergoing an Ultrasound

Dr. Sanjay Singhvi emphasizes that ultrasound is a simple and harmless procedure. However, it is crucial to keep a few things in mind before the examination.

ere are the key considerations:

Ultrasound on an Empty Stomach:

It is generally recommended to undergo ultrasound on an empty stomach.

Although exceptions may be made for emergency cases, patients are often advised to fast before ultrasound procedures involving the kidney, intestine, stomach, or uterus.

This is because the gallbladder contracts after eating, making it difficult to obtain accurate scans of gallbladder diseases.


If you have an ultrasound appointment the next day and have already consulted with your doctor, they may advise you to come on an empty stomach but allow water intake.

While fasting, acidity can be a concern for some individuals.

If you experience acidity issues, it is advisable to avoid undergoing ultrasound. However, if you do not face such problems, drinking a small amount of water is permissible.

Ensure you stay well-hydrated by consuming an ample amount of water before your appointment. Adequate hydration is particularly crucial for stomach-related conditions.

Comfortable Attire:

When preparing for an ultrasound, it is important to wear loose-fitting clothes.

The area where the ultrasound will be conducted will require you to remove clothing, so plan accordingly to ensure maximum comfort.

Post-Ultrasound Care

After undergoing an ultrasound, there are generally no significant side effects or complications. It is a safe procedure that does not result in body heat elevation or other noticeable adverse reactions.


Understanding the factors associated with an ultrasound examination can help alleviate any concerns or doubts you may have.

By following the expert advice provided by Dr. Sanjay Singhvi, you can ensure a smooth and successful ultrasound experience.

Remember to consider fasting, maintain proper hydration, and wear comfortable clothing to enhance your comfort during the procedure.

Ultrasound is an invaluable tool in diagnosing and monitoring various medical conditions, making it an essential part of modern healthcare.
