Causes of Dizzy Spells and Headaches

There are many people who suffer from headaches and dizziness, and quite often they don’t know the root cause. There are a variety of conditions that can cause these symptoms, so it is important to make an appointment with your medical professional to find out the underlying reasons before you make assumptions. The following can give you some background to what might be causing your symptoms.

Causes of Dizziness

Some of the main reasons people may experience dizziness include:

  • Anxiety and hyperventilation
  • Heart conditions, such as high or low blood pressure
  • Diabetes
  • Dehydration

Having low blood pressure may lead to postural hypotension or dizziness which is a result of moving from a sitting or lying down position to standing.

Causes of Headaches

Some of the main causes of headaches include:

  • Poor posture – Tension headaches may occur from sitting at a desk for example, where your seating and viewing of a computer screen is not ergonomically correct
  • Frequent stress
  • Exposure to allergens or chemical irritants
  • Certain foods.

The Dizzy Sensation

Individuals who suffer from dizzy spells may feel like they are going to faint. Quite often a headache may accompany a dizzy spell.

Some people who experience the room spinning may have a condition known as vertigo. If you notice you are dealing with a headache and are dizzy simultaneously, it may be a symptom of a more severe medical condition.

Keeping Track Of Your Episodes

It’s a good idea to keep a diary of your dizzy and headache experiences. Take note of what you were doing when it started, what you had recently eaten, etc.

You may notice a pattern if you do this. Perhaps there will be a trend of what time of day this occurs, or if you have these episodes on days you are extremely busy or stressed, or if you haven’t had enough water to drink.

Acute Conditions

  • Anxiety

Being anxious or extremely worried can lead to an increased heart rate, sweating, as well as dizzy spells or headache. Many people forget to eat and drink at regular intervals during a stressful situation. With a hectic lifestyle and unrealistic deadlines, it is easy to become overwhelmed. Combined with lack of sleep, they may experience these symptoms.

  • Insufficient Sleep

Experiencing occasional headaches and dizziness may result after insufficient sleep. Many people work late into the night on computers or reading their iPad or eReader, and the artificial light can eventually disrupt their circadian rhythms. Try to limit your exposure to the blue spectrum of light in the hours before bedtime and incorporate a relaxing bedtime routine.

  • Dehydration

It can be easy to become dehydrated if you are drinking an excess of diuretics such as tea or coffee, sweating extensively from extended cardio workouts, or eating salty foods. If you do not replenish your fluid intake, you may suffer the consequences.


  • Low Blood Pressure

Some people naturally have lower blood pressure than others. However, it can cause them to have a headache or feel dizzy, especially when changing positions. When their blood pressure drops below normal, at the extreme, unconsciousness may occur. It’s important to watch for warning signs!

  • Medication Side-Effects

Dizzy spells and headaches may be triggered by specific medications. It is something to speak with your doctor about if you have recently started a new prescription and are having these symptoms.

Whatever the reason for your headaches, it is far preferable to know what is causing them so you can focus on fixing the problem, rather than simply treating the resulting symptom of headache with an analgesic.
