In the USA, they decided to fight constipation with the help of vibrating capsules.

They do not contain active drugs. They force the intestines to empty, affecting nerve cells and causing muscle contractions. Capsules should be taken orally every day. They reach the large intestine in about 14 hours. After that, they start working. During the tests, the capsules were programmed for several vibration sessions - three seconds after three. The sessions lasted a couple of hours. The capsules were passed out of the body along with the faeces.
