Using a TENS Machine to treat Nausea

Nausea and vomiting are symptoms of many conditions such as:

  • Motion sickness or seasickness
  • Early stages of pregnancy (nausea occurs in approximately 50%-90% of all pregnancies; vomiting in 25%-55%)
  • Medication-induced vomiting
  • Result of an anaesthetic
  • A TENS machine can be used to treat nausea by placing the black electrodes over an easily found acupuncture point. If you turn your hand palm up you will notice that there are two or three skin ceases where the wrist bends. Place the black electrode so that its centre is approximately 2inch above the middle of the crease which is closest to the hand. The red electrode may be placed 6inch higher or over the fleshy part of the hand just below the thumb.
