MRI (Magnetic Resonance Imaging) is a widely used and non-invasive imaging technique that helps doctors obtain detailed pictures of the inside of your body. Whether you’re undergoing an MRI to assess an injury, illness, or for general diagnostic purposes, it’s a critical tool in modern healthcare. However, some people report feeling drained, fatigued, or weak after an MRI. If you’ve ever asked yourself “why do I feel drained after an MRI?”, you’re not alone.
This article will explore the potential causes of post-MRI fatigue, provide insights into the procedure itself, and offer tips for recovery. We aim to help you understand the connection between MRI and feelings of exhaustion, so you can feel more informed and prepared next time you’re scheduled for an MRI.

Introduction
Many patients wonder, “why do I feel drained after an MRI?” The answer to this question depends on a variety of factors, including the nature of the MRI procedure, your body’s reaction to it, and your overall health. While MRIs are safe and effective, some individuals experience feelings of tiredness or weakness afterward. In this article, we will discuss the common reasons behind this sensation, how long the fatigue might last, and what steps you can take to recover more quickly.
Understanding these factors can help reduce any anxiety you may have about the procedure and reassure you that fatigue is usually a temporary side effect. Read on to learn more.
What is an MRI?
Before diving into the reasons behind post-MRI fatigue, it’s important to understand what an MRI is and how it works.
An MRI is a medical imaging technique that uses strong magnetic fields and radio waves to create detailed images of organs, tissues, and structures inside the body. Unlike X-rays or CT scans, MRIs don’t use radiation, making them a safer alternative for certain imaging needs.
During the procedure, you lie down on a table that slides into a large MRI machine. The machine takes a series of images, which can take anywhere from 30 minutes to over an hour, depending on the area being scanned.
Types of MRIs
There are different types of MRIs, and the experience may vary based on the specific type you’re undergoing. Some common MRI types include:
- Standard MRI: This uses magnetic fields to generate images without the use of a contrast agent.
- MRI with Contrast: A contrast agent (usually gadolinium) may be injected to enhance the quality of the images.
- Functional MRI (fMRI): This measures brain activity by detecting changes in blood flow.
The most common reason for feeling drained after an MRI is related to the type of MRI you’re having, how long the procedure lasts, and your body’s response to it.
Common Causes of Fatigue After an MRI
Now that you understand what an MRI is, let’s explore the reasons why you may feel drained after the procedure.
1. The Length of the MRI Procedure
One of the main reasons for fatigue after an MRI is the length of the procedure. An MRI can take anywhere from 30 minutes to over an hour, depending on the area being scanned. Lying still for such a long time, especially if you’re uncomfortable or anxious, can be physically exhausting. Your muscles may become tense, and the mental strain of staying still and focused can also contribute to feelings of fatigue.
2. Anxiety or Stress During the Procedure
Many people feel anxious before or during the MRI. The noise inside the machine, the feeling of being in a confined space, and the thought of the results can cause stress. The body’s natural response to stress is to release stress hormones like adrenaline and cortisol. After the procedure, once these hormones return to normal levels, you may experience fatigue or an emotional “crash” that makes you feel drained.
3. The Use of a Contrast Agent
In some cases, MRIs are performed with a contrast agent, usually gadolinium, to enhance the quality of the images. While these agents are generally safe, they can cause mild side effects for some people, including nausea, dizziness, or fatigue. The body works to process and eliminate the contrast agent, which can be a drain on your energy levels. Dehydration can also occur after receiving contrast agents, which can further contribute to feelings of tiredness.
4. Dehydration
Dehydration can be a common cause of fatigue after an MRI. The contrast agent used in some MRIs is eliminated through the kidneys. As your kidneys work to filter and expel the contrast, you may become dehydrated, especially if you didn’t hydrate properly before or after the procedure. Dehydration leads to fatigue, dizziness, and a general feeling of weakness.
5. Underlying Health Conditions
If you have any pre-existing health conditions, such as chronic fatigue, anemia, or kidney problems, you may be more susceptible to feeling drained after an MRI. For example, people with kidney disease may experience delayed elimination of the contrast agent, leading to prolonged fatigue. If you already feel tired due to an underlying condition, the MRI procedure could exacerbate these feelings.
6. Hormonal Changes Due to Stress
Stress and anxiety can trigger the release of certain hormones in your body, like cortisol and adrenaline, as part of the “fight or flight” response. While these hormones help you manage stressful situations, they can leave you feeling drained once the stressor is over. Your body requires energy to return to its normal state, and this process can contribute to post-MRI fatigue.
7. Post-Procedure Recovery Time
The time your body needs to recover from the MRI procedure also plays a role in how you feel afterward. For some people, it may take several hours to fully recover from the procedure. This is especially true if you’ve had a lengthy or particularly stressful MRI session.
How Long Does Fatigue Last After an MRI?
In most cases, fatigue after an MRI is temporary and will resolve within a few hours to a day. However, if you continue to feel tired or drained for an extended period, or if other symptoms arise, it’s important to reach out to your healthcare provider.
If your fatigue persists, your doctor may recommend additional tests or examinations to ensure there are no underlying issues contributing to your symptoms.
Tips for Recovering from Fatigue After an MRI
If you’re feeling drained after your MRI, there are a few things you can do to speed up your recovery:
1. Stay Hydrated
After the procedure, drinking water helps to flush out the contrast agent and prevent dehydration. Aim to drink plenty of fluids throughout the day to support your body’s recovery process.
2. Rest and Relax
Give your body time to recover by taking it easy. If you feel tired, allow yourself some rest. Avoid strenuous activities or physical exertion until you regain your energy.
3. Eat Healthy, Energizing Foods
A well-balanced meal can help replenish your energy. Focus on foods high in protein, complex carbohydrates, and essential vitamins and minerals. Eating healthy will give your body the nutrients it needs to recover.
4. Practice Relaxation Techniques
If you feel stressed or anxious about the procedure, try deep breathing exercises or meditation. These techniques can help calm your body and reduce any lingering feelings of exhaustion caused by stress.
When Should You Seek Medical Attention?
While post-MRI fatigue is usually mild and temporary, it’s important to be aware of any unusual symptoms that could indicate a problem. Seek medical attention if you experience:
- Persistent fatigue lasting more than a day
- Severe headaches, dizziness, or nausea
- Pain, swelling, or redness at the injection site (if contrast was used)
- Difficulty breathing or chest pain
These could be signs of a reaction to the contrast agent or another health issue that requires medical attention.
