Dizziness in fibromyalgia is common and treatable, though it often requires a combination of approaches rather than a single fix. The dizziness typically stems from problems with blood pressure regulation, where your body struggles to maintain steady blood flow to the brain when you stand up or change positions. This is called orthostatic intolerance, and it overlaps heavily with fibromyalgia. Some medications used for fibromyalgia itself, including certain antidepressants and pain medications, can also contribute to or worsen dizziness.
Why Fibromyalgia Causes Dizziness
The nervous system in people with fibromyalgia often has trouble regulating automatic functions like blood pressure and heart rate. When you stand up, your body is supposed to quickly tighten blood vessels and slightly increase your heart rate to keep blood flowing to your brain. In fibromyalgia, this response can be sluggish or insufficient, causing a temporary drop in blood pressure that makes you feel lightheaded, unsteady, or like the room is spinning.
This isn’t just a minor inconvenience. Repeated episodes of dizziness increase fall risk, limit your ability to exercise (which is one of the most effective fibromyalgia treatments overall), and can make daily tasks like cooking or showering feel unsafe. Addressing it directly can improve your quality of life in ways that go well beyond just reducing the spinning sensation.
Fluid and Salt Intake
The simplest and most effective first step is increasing how much fluid and salt you consume. Both help expand your blood volume, which makes it easier for your body to maintain adequate blood pressure when you change positions. Current guidance for people with orthostatic intolerance recommends 2 to 3 liters of fluid per day and 6 to 10 grams of additional salt daily. For reference, 6 grams of salt is roughly one level teaspoon.
This is significantly more salt than what’s typically recommended for the general population, so it’s worth confirming with your doctor that your heart and kidneys can handle the increase. For most people with fibromyalgia-related dizziness and no cardiovascular issues, the benefits are substantial. Spreading your fluid intake throughout the day works better than drinking large amounts at once. Water is fine, but drinks with electrolytes can help you retain more of what you consume.
Movement Strategies That Help
How you move matters as much as how much you move. A few behavioral changes can significantly reduce dizzy episodes:
- Get up in stages. When rising from bed, sit on the edge for 30 seconds before standing. When getting up from a chair, pause before walking. This gives your cardiovascular system time to adjust.
- Tense your leg muscles before standing. Crossing your legs and squeezing, or pumping your calves a few times while seated, pushes blood back toward your heart and brain before you’re upright.
- Avoid prolonged standing. If you need to stand in one place (waiting in line, cooking), shift your weight, rock on your heels, or march gently in place to keep blood circulating.
Regular physical activity also helps over time. Walking, water-based exercise, and tai chi all improve strength, balance, coordination, and flexibility, which collectively reduce both dizziness frequency and fall risk. If you’ve been avoiding activity because you’re worried about falling or triggering a flare, a physical therapist can design a program that starts gently and builds gradually. Supervised programs are especially useful because they address the specific balance deficits that dizziness creates.
Medication Review
Several medications commonly prescribed for fibromyalgia can make dizziness worse. Certain antidepressants, sedatives, antihistamines, and muscle relaxants all have the potential to lower blood pressure, cause drowsiness, or affect your coordination. If your dizziness started or worsened after beginning a new medication, that connection is worth investigating.
Bring a full list of everything you take, including over-the-counter drugs and supplements, to your next appointment. Your provider can review for side effects and interactions that increase dizziness or fall risk, and may be able to adjust doses, switch medications, or wean you off ones that are contributing to the problem. Sometimes a simple timing change (taking a medication at bedtime instead of in the morning) makes a noticeable difference.
When Blood Pressure Support Is Needed
If lifestyle measures and medication adjustments don’t resolve the dizziness, your doctor may consider prescribing something specifically to support your blood pressure. One option is a medication that tightens blood vessels to prevent the pressure drop that happens when you stand. These are typically taken during daytime hours only, spaced about four hours apart (morning, midday, and late afternoon), because raising blood pressure while lying flat overnight can cause problems.
Another approach uses a medication that helps your body retain salt and fluid, effectively doing what the dietary changes aim to do but more aggressively. Both options require monitoring because they can raise blood pressure too much in some people. These medications aren’t first-line treatments, but they can be very effective for people whose dizziness significantly limits their daily function.
Compression Garments
Waist-high compression stockings or abdominal compression bands help prevent blood from pooling in your legs and abdomen when you stand. They work on the same principle as tensing your leg muscles: they physically push blood back toward your upper body. Knee-high compression socks are easier to find and wear but less effective than waist-high options, because a large portion of blood pools in the abdomen rather than the lower legs.
Compression garments can be uncomfortable, especially in warm weather, and putting them on can be difficult if you have hand pain or stiffness from fibromyalgia. Wearing them during the hours you’re most active and most likely to experience dizziness (rather than all day) is a reasonable compromise.
Reducing Fall Risk at Home
While you work on treating the underlying dizziness, making your home safer prevents injuries from the episodes you do have. This is especially important in fibromyalgia because the combination of dizziness, fatigue, and joint pain creates a higher fall risk than dizziness alone.
Start with the bathroom, where most falls happen. Use nonslip mats in the tub or shower, and consider a bath seat so you can sit while showering. In the rest of your home, remove loose rugs or secure them with double-faced tape, clear walkways of cords and clutter, and keep frequently used items within easy reach so you’re not stretching or climbing. Good lighting matters more than most people realize. Place night lights in your bedroom, bathroom, and hallways, and keep a lamp within reach of your bed so you’re never navigating in the dark.
Footwear plays a role too. High heels, floppy slippers, and shoes with slick soles all increase fall risk. Flat, sturdy shoes with nonslip soles are the safest option, and they can also reduce the joint pain that makes it harder to catch your balance. Walking around in socks or stockings on hard floors is one of the most common fall hazards.
