Headache & Dehydration

LOCATION AND SYMPTOMS

Generalised headache – headaches are one of the symptoms of dehydration.

PRECIPITATING FACTORS

Dehydration is caused by a lack of fluid intake or excess fluid losses. You are most likely to lose fluid through vomiting, diarrhoea, sweat and urine. Many cases of dehydration are caused by: heat, vomiting and diarrhoea (i.e. ‘gastro’), fever, vigorous exercise or strenuous activity, alcohol consumption (alcohol acts as a diuretic), travel (travellers’ diarrhoea, long-haul flights – dry cabin conditions, sun exposure, physical activities and alcohol consumption) or lack of food/fluid intake.

TREATMENT / PREVENTION

Under normal circumstances a ‘good hydration status’ can be adequately achieved with water and a balanced diet. However, if you are at risk of dehydration, an oral rehydration solution (Hydralyte™) will have some advantages, including:

  • Rehydration is likely to be more rapid
  • The retention of water is better.
