Unraveling the Connection Between Dehydration and Back Pain

Unraveling the Connection Between Dehydration and Back Pain


Up to 80% of adults experience back pain at some point. Its causes are varied. Dehydration may be a cause. The American Chiropractic Association (ACA) says this.

One in four Americans get lower back pain in 3 months. 33% have chronic back pain. But few know dehydration and back pain can be linked.

Studies show dehydration weakens bodies. This makes them less able to cope with physical strain. This can create microtrauma over time. This can worsen existing chronic back pain or start new cases.

Research suggests hydration, performance and injury recovery are linked. If you don’t stay hydrated, you may get headaches or nausea. This can limit performance more than muscle fatigue would. To avoid fatigue, reduce injury risk or just improve wellbeing while exercising – drink lots of water.

What is Dehydration?

Dehydration is when your body lacks water or fluid. Water is essential for organs to operate, keep body temperature regulated, remove toxins, and make muscles work.

In this article, we’ll explore how dehydration and back pain are connected.

Causes of Dehydration

Dehydration occurs when fluids leave the body faster than they are taken in. Our bodies need water to work properly, and if we don’t get enough, it can cause serious health issues. Causes of dehydration include sweating too much, being sick, having a fever, having diarrhea, not drinking enough liquids and taking certain medicines. People of all ages can get dehydrated, but infants, young children and the elderly have a greater risk. It is important to recognize the signs of dehydration so it can be taken care of quickly.

Signs of dehydration in adults:

  • Less pee or pee that is dark
  • Dry mouth
  • Headache
  • Tiredness
  • Lack of alertness
  • Muscle cramps

In babies and young children, there may be less tears when crying, dry skin, irritability or fatigue. If it’s not treated, severe dehydration can result in shock (marked by a low body temperature) or even death. The elderly are especially vulnerable to dehydration, because they are less likely to feel thirsty and may also have medical conditions such as diabetes.

Symptoms of Dehydration

Dehydration is an alarming condition caused by lack of water in the body. It has a huge effect on the entire body and brings about a variety of painful symptoms. Knowing what to look out for is essential to avoid and treat dehydration correctly.

Typical signs of dehydration are:

  • Feeling thirsty/having a dry mouth.
  • Being tired, slow or grumpy.
  • Suffering from headaches/dizziness/lightheadedness.
  • Having dark yellow urine or going to the toilet less often.
  • Experiencing muscle cramps, twitches or spasms.
  • Having dry eyes, skin and mouth tissue (chapped lips).
  • Reduced sweating.
  • Having sunken eyes and wrinkles on the side of the nose when smiling (skin elasticity test).
  • Low blood pressure/fast heartbeat when standing or feeling faint when standing quickly (orthostatic hypotension).

If left untreated, dehydration can lead to swelling of organs (edema), electrolyte imbalances (like low sodium levels), kidney failure, shock and coma in extreme cases. It can also cause related issues such as back pain due to disc dehydration, which can cause sciatica, spinal stenosis and other chronic backache if not reversed through rehydration treatments like intradiscal injection therapies etc. Early recognition and treatment are necessary to manage mild to moderate dehydration before it becomes too serious and leads to long-term health issues.

How Does Dehydration Affect Back Pain?

Dehydration’s effects on your body are noteworthy, especially when it comes to back pain. When your body has a lack of water, your muscles aren’t functioning properly. This can bring on back pain. Also, dehydration makes connective tissue in your body weak, so it can’t support your frame like it would if it were properly hydrated.

Let’s explore how dehydration can cause and/or worsen back pain further:

Dehydration and Lower Back Pain

Back pain and dehydration are closely related. Our bodies contain 60-75% water, depending on age and body composition. When we’re dehydrated, so is our body, including the spine muscles and cartilage. These can compress or pull out of alignment, leading to chronic pain.

Inflammation throughout the body caused by dehydration can lead to back pain. Swelling around the vertebrae may irritate nerves. Also, proteins may irritate receptors on either side of the spine.

Severe dehydration could cause other issues such as:

  • Low blood pressure
  • Tachycardia
  • Kidney stones
  • Low levels of minerals

All these could lead to lower back problems. Thus, staying hydrated is essential for a healthy spine.

Dehydration and Upper Back Pain

Dehydration occurs when the body lacks enough water. This can lead to physical symptoms, including back pain. When dehydrated, the body takes water away from parts that don’t need it, like the spine joints. This causes lower back muscles to contract, resulting in tightness or stiffness in the upper back.

Dehydration also causes tension headaches. Plus, it reduces the elasticity of ligaments, which leads to limited motion and pain in the upper back.

How to Treat Dehydration-Related Back Pain

Dehydration? Major impact! Your body could feel it. Back pain? Yes, that too. When dehydrated, your muscles and discs don’t balance. As a result, tightness and pain.

Dehydration the cause of your pain? Treatment options exist. Let’s look into it. Learn more about the link between dehydration and back pain. Plus, the treatment options.

Drink Plenty of Water

Drinking plenty of water is key for managing back pain related to dehydration. Adults should have roughly 3 liters (11 cups) per day for men and 2.2 liters (9 cups) per day for women. In hot summer months, or when exercising, even more may be needed.

Focus on quantity of fluids, not just quality. Any non-alcoholic beverage can help hydrate, like water, tea, or juice. Avoid caffeine, alcohol, and sugar to stay hydrated.

In addition, add a pinch of sea salt or some coconut water to drinks for electrolytes. Eating foods with high water content can also help increase fluid intake:

  • Cucumbers
  • Celery
  • Tomatoes
  • Strawberries
  • Watermelon
  • Cantaloupe
  • Oranges
  • Grapefruit

Eat Foods Rich in Electrolytes

Eating foods rich in electrolytes can help reduce dehydration-related back pain. Examples of these foods are:

  • Bananas
  • Figs
  • Carrots
  • Celery
  • Potatoes
  • Leafy greens
  • Fatty fish
  • Nuts
  • Dairy products
  • Yogurts
  • Cheeses
  • Milk
  • Eggs
  • Oranges
  • Apples
  • Strawberries

You can also take electrolyte supplements to stay hydrated. Sports drinks, energy gels, and powders contain sodium and potassium for optimal hydration levels. Read labels carefully before taking any form of supplementation.

To stay hydrated, drink 33 oz of fluids throughout the day. Also, eat plenty of nutrient-rich foods. This will help you maintain optimal hydration levels.

Take Anti-Inflammatory Medications

Dehydration-related back pain can be severe. Treatment is usually simple. Taking medications, like ibuprofen, naproxen sodium, acetaminophen, or aspirin, helps reduce swelling and muscle spasms. See a doctor if the pain is severe, as it may be from an underlying health issue.

Physical therapy and massage can help realign the spine and increase blood flow. Hydration alone won’t fix the problem. Good posture and stretching are also important:

  • Maintain good posture when sitting and standing.
  • Perform gentle stretching exercises.
  • Take frequent breaks from sitting.
  • Do exercises to strengthen the core muscles.

Seek Professional Help

Dehydration-related back pain needs medical attention. A physical exam and imaging tests like X-rays or MRIs may be necessary. They can diagnose underlying conditions causing the pain and may need medication or surgery. Your healthcare provider can help manage the pain with lifestyle changes and keeping your body hydrated. They may suggest NSAIDs for long-term relief. Physical therapy may be helpful for muscle spasms or other contributing factors.

To get long-term relief, it is important to speak to a healthcare professional about the causes and treatments of dehydration-related back pain.


It’s clear: dehydration and back pain are linked. Excessive sweating, heat, exercise, fever, or chemo side effects are all causes of dehydration. This leads to tight muscles and spasms, causing awful pain.

To avoid this, drink water often and keep hydrated. Exercise and stretch often as well, to help muscles handle strain. Plus, good posture helps reduce stress on the spine and lower back.

By taking these steps, you can prevent dehydration-related back pain.
