Hydration IV in Seoul, when drinking is not enough

When a hydration IV in Seoul helps

Of all the drips on offer, fluid replacement has the clearest medical basis. A hydration IV in Seoul replaces water and salts such as sodium and potassium directly into the bloodstream, which can help when you are losing fluid faster than you can drink it, or when nausea means nothing stays down.

Common situations include a bout of food poisoning or stomach flu, heat exhaustion during Seoul's humid summer, a long hike or race in hot weather, or a long-haul flight followed by little food and drink. Dr. HyunSung Park, a board-certified internal medicine specialist and gastroenterology subspecialist, assesses how dehydrated you are, looks for the cause and decides what type and volume of fluid is safe. If vomiting is the main problem, he may add an anti-nausea medicine.

Signs you may be dehydrated

Mild dehydration usually responds well to sipping an oral rehydration solution, available in Korean pharmacies, little and often. Plain water alone replaces fluid but not the salts lost through sweat, vomiting or diarrhea. If you cannot keep fluids down for several hours, or symptoms are getting worse, a medical assessment is the right next step.

• Thirst, a dry mouth and dark yellow urine
• Passing urine much less often than usual
• Dizziness or lightheadedness when you stand up
• Headache, tiredness and muscle cramps
• A fast pulse or feeling weak after vomiting or diarrhea

Oral rehydration or a drip?

For most healthy adults with mild to moderate dehydration who can drink, oral rehydration works as well as IV fluids and avoids a needle. A drip makes more sense when vomiting prevents drinking, when you feel faint, or when you need to recover quickly for travel or an important event. The doctor will tell you honestly which approach fits your situation.

Extra vitamins are not needed to rehydrate. If they are requested, Dr. Park will explain that the evidence for adding them in healthy people is limited, and that the fluid and electrolytes do most of the work.

Whichever route you take, recovery continues at home. Keep sipping fluids through the rest of the day, aiming for pale yellow urine. Start with bland, easy foods such as rice porridge, crackers, bananas or clear soup, and return to your normal diet as your appetite allows. Avoid alcohol and very sugary drinks until you feel well, as both can make diarrhea worse. If you are traveling, plan a lighter schedule for a day and carry a bottle of electrolyte drink with you, especially in summer.

Who it suits and who should not have it

A hydration drip suits otherwise healthy adults with dehydration from a clear, short-term cause. More caution is needed, and sometimes a hospital is the safer place, if you have heart failure, kidney disease, liver cirrhosis or uncontrolled high blood pressure, because extra fluid or salt can be harmful. Tell the doctor if you are pregnant or breastfeeding, take diuretics or blood thinners, or have G6PD deficiency if any vitamin C is being considered. Older adults and people with diabetes can become dehydrated more quickly and may also need blood tests.

Severe dehydration: call 119

Some signs mean you need an emergency room rather than a clinic drip. Call 119 for confusion or extreme drowsiness, fainting, no urine for many hours, a racing heart at rest, vomit containing blood or black stools, severe abdominal pain, or a high fever with a stiff neck. Heatstroke, with hot skin, confusion and stopped sweating, is an emergency: move the person somewhere cool and call 119 straight away.

For diarrhea lasting more than a few days, or with blood, the doctor may arrange stool or blood tests to look for an infection. Total cost depends on the fluids and any medicine used, and we explain the full price before treatment.
