Rheumatoid arthritis (RA) is a chronic autoimmune condition that affects your joints and can impact other parts of your body. It requires medical treatment to manage symptoms, but certain lifestyle factors can impact your well-being with RA.

Hydration is not directly linked to RA flares, but drinking enough water may help you feel better, reduce inflammation, and keep your joints cushioned.

Dehydration can also cause symptoms, so it’s important to try to prevent the condition to avoid experiencing them.

Drinking enough water helps your body function properly.

Water helps cushion your joints, which RA and other types of arthritis affect. It’s important to keep your joints working as well as possible when you have RA or other joint-related conditions.

Water can also help reduce inflammation in your body by flushing out toxins. Inflammation can cause joint swelling and discomfort.

Dehydration is a condition that occurs when your body does not have enough fluid. You may experience dehydration because of:

  • being in hot weather
  • having a gastrointestinal illness that causes vomiting, diarrhea, or urinating too frequently
  • taking a medication that causes you to urinate too much
  • sweating a lot
  • having a fever
  • failing to drink enough water daily

Symptoms of dehydration include:

  • thirst
  • dry lips and skin
  • lightheadedness
  • dizziness
  • fainting
  • fatigue

Fatigue is also a symptom of RA.

To treat dehydration, you need to take in more fluids. Mild cases of dehydration can be treated with drinking fluids at home. Severe dehydration may require you to visit a hospital to receive intravenous (IV) fluids.

There are no proven links between RA and dehydration, but making lifestyle choices that provide health-promoting benefits is important in managing RA and keeping your joints working well. Staying hydrated is one way to make sure your body functions properly.

Hydration not only impacts joints, but it contributes to your energy levels and regulates your body temperature. RA can cause fatigue and fevers during flares, and you may avoid experiencing those symptoms from dehydration if you drink plenty of water daily.

Exercise is a common recommendation for managing RA symptoms. Exercising in hot weather or for long enough that you sweat a lot can make you vulnerable to dehydration. Make sure you drink water during and after exercise to avoid dehydration symptoms.

Drinking water alone will not manage RA symptoms. RA requires medical support from a doctor to help manage and stop the condition from getting worse.

The amount of water you need to drink every day depends on your individual needs.

RA does not impact water levels, so your needs for water may be similar to someone without the condition. Keep in mind that nonsteroidal anti-inflammatories (NSAIDs) can cause water retention, so your hydration needs may change if you take these medications for RA symptoms.

There is general guidance to drink eight glasses of water a day, but this can fluctuate depending on your needs. You may not need to drink eight glasses of water straight from a cup or water bottle. Fruits and vegetables contain water, too, and other beverages also count toward your daily water consumption.

Here are some tips to consider for getting enough water throughout the day:

  • Drink water all day long, including before breakfast, at meals, and in-between.
  • Add other low calorie beverages to your daily routine, including tea, coffee, or seltzer water. There is no conclusive research linking RA symptoms with coffee or tea consumption.
  • Use a few slices of fruit to add flavor to your water.
  • Avoid sugary drinks like juices and soda, as their calories can also add up in your overall diet.
  • Carry a water bottle with you wherever you go.

Replacing fluids your body loses (expels) when you use the bathroom and sweat is important to consistently keep a healthy level of fluid in your body. This means you should drink several glasses of water a day and add more to your routine if you’re exercising or in hot weather.

Talk with a doctor if you have a gastrointestinal illness that’s preventing you from keeping fluids in your body. Frequent diarrhea and vomiting can lead to dehydration. You may need to drink more water or sports beverages to restore needed electrolytes in your body.

Certain environmental factors can cause RA flares. Triggers can include:

If you have RA, your body may feel best when you’re taking good care of yourself. Eating a nutritious diet that helps you maintain a moderate weight, staying physically active, and getting enough sleep may help in managing your symptoms.

You can have both RA and dehydration, but they are not necessarily linked. Here are some other questions related to these two conditions.

Does how much water you drink affect other types of arthritis?

Water consumption helps your body function, and that can have an impact on other types of arthritis. Make sure you get enough water to help cushion your joints and keep your body functioning properly.

Can dehydration cause other types of joint pain?

Water consumption can affect the cushioning of your joints. Therefore, you may have joint pain because of a lack of water.

How do you tell if you’re dehydrated?

You may feel thirsty, tired, or sluggish (lethargic) if you’re dehydrated. Your skin or lips might feel dry. Severe dehydration may lead to you fainting and losing consciousness.

RA and dehydration are two separate medical conditions. Both can affect your joints and energy levels.

Dehydration can be treated by an increased intake of fluids, and in severe cases, it may require you visiting a hospital to receive IV fluids.

RA is a lifelong condition that requires a doctor-prescribed treatment plan.

RA may be improved by engaging in lifestyle habits that provide health-promoting benefits like drinking enough water each day while also following your doctor-prescribed treatment plan.
