Lightheadedness and fatigue: Man with hands on his head feeling dizzy

Lightheadedness and fatigue are among the most common health complaints — and they can also indicate a serious underlying issue. However, millions of Americans attribute feelings of tiredness to disruptions in their daily activities. Whether you wake up feeling sluggish or constantly feel like you just don’t have enough energy, conditions like dehydration may be behind these symptoms. 

Here, we’ll show you the main causes of lightheadedness and fatigue ranging from medical conditions to side effects of medications. You’ll learn how being dehydrated can contribute to these symptoms and why using an oral rehydration solution like DripDrop ORS is the best solution for dehydration-related dizziness and fatigue. It enables you to treat mild to moderate dehydration at home, helping you avoid a more serious condition that results in an emergency room visit for IV therapy.

Causes of Lightheadedness and Fatigue

There are many medical conditions and factors that may cause lightheadedness and fatigue. Some medications include these symptoms as side effects while certain medical conditions can cause tiredness and dizziness. If your symptoms are chronic, you might have an underlying medical condition. For short-term fatigue and dizziness, dehydration may be the root cause.

Here are some of the possible causes of lightheadedness and fatigue:

  • Dehydration
  • Chronic fatigue syndrome (CFS)
  • Orthostatic hypotension (a condition where blood pressure drops when you stand up)
  • Hypoglycemia (low blood sugar levels)
  • Low blood pressure
  • Anemia and iron deficiencies 
  • Concussions and head injuries
  • Heart disease or heart attack
  • Migraine headaches and other severe headaches
  • Medications including antidepressants, sleeping pills, muscle relaxants, and antihistamines
  • Sleep problems including insomnia
  • Conditions that affect the inner ear including Benign paroxysmal positional vertigo (BPPV), Meniere’s disease, vestibular neuritis, tinnitus, and labyrinthitis

Often, lightheadedness and fatigue are simply the results of not drinking enough fluids and electrolytes. However, if your symptoms are accompanied by chest pain, shortness of breath, double vision, or seizures, it’s a good idea to seek medical advice from a qualified healthcare professional. An irregular heartbeat, irregular heart rhythm, and heart palpitations may also be a cause for concern. Talk to a doctor if your lightheadedness and fatigue are paired with these symptoms.

If your lightheadedness and fatigue aren’t caused by medical conditions, your symptoms are likely the result of dehydration. Fortunately, you can avoid costly and time-consuming hospital visits for IV treatments by using an oral rehydration solution like DripDrop ORS to manage dehydration. It contains medically relevant amounts of electrolytes to support hydration, helping to fend off and address dehydration symptoms including lightheadedness and fatigue.

Why Dehydration May Be the Culprit

Lightheadedness and fatigue are among the most common symptoms of dehydration and — barring any underlying medical conditions — likely the reason you’re feeling tired or experiencing dizzy spells. Dehydration is a condition where you lose more water and electrolytes than you’re taking in. Other common symptoms of dehydration include extreme thirst, headache, muscle and joint pain, loss of consciousness, lightheadedness, and fatigue.

Here’s how being dehydrated may cause you to feel tired, lightheaded, or off-balance. When you’re dehydrated, your blood pressure drops, limiting your body’s ability to circulate blood and decreasing blood flow to your nervous system. That means your brain can’t send signals across neurotransmitters as effectively as normal, resulting in foggy and sluggish thoughts and movements. Lower blood flow to your brain can also produce feelings of lightheadedness and dizziness as your brain is deprived of oxygen and nutrients that are transported through your bloodstream.

In addition, dehydration decreases your normal blood fluid volume levels, particularly in red blood cells. These cells contain fluid that is made of electrolytes including sodium, potassium, and magnesium as well as water. Your body needs these electrolytes and fluids to carry out normal functions including muscle movement and water retention. When your blood fluid volume drops, your heart has to work harder to pump nutrients and fluids through your blood vessels and arteries, causing fatigue.

Dehydration can also affect your ability to perform exercises and daily tasks. In fact, a meta-analysis published in the Journal of Sport and Science Health found that dehydration decreased VO2 max — the maximum rate of oxygen your body can use during intense exercise and a key indicator of overall fitness performance. That means you’ll fatigue sooner than normal when you’re dehydrated. Dehydration can also cause muscle cramping that further reduces your performance and leads to fatigue.

If you suspect your lightheadedness and fatigue are the result of dehydration, there’s an easy and affordable remedy. Drink an oral rehydration solution like DripDrop ORS, which contains precise amounts of electrolytes that your body needs to manage dehydration. The convenient packaging makes it easy to put in a bag, so you can always have a top-of-the-line dehydration protocol at your fingertips.

How To Avoid Dehydration and Resulting Fatigue

It’s easier than you may think to become dehydrated. While older adults and young children are more susceptible to the condition, we can all experience dehydration, especially if we aren’t replenishing fluids and electrolytes as quickly as we lose them. Common causes of dehydration include illnesses that cause diarrhea and vomiting, excessive sweating, not drinking enough fluids, and strenuous physical activity — especially outdoors in high or cooler temperatures. 

The best way to avoid dehydration — and the fatigue and lightheadedness that come with it — is to drink an oral rehydration solution like DripDrop ORS. It’s a better choice than water and fruit juice or sports drinks thanks to its medically relevant formulation.

Plain water doesn’t contain many electrolytes that you lose when sweating or when you’re sick. Fruit juices and sports drinks have too much sugar and not enough of the right electrolytes to remedy dehydration. DripDrop ORS was developed by a doctor and contains precise ratios of electrolytes to relieve dehydration fast. By comparison, sports drinks contain about one-third the electrolytes of DripDrop ORS and twice as much sugar.
