Contraindications to ultrasonic cavitation are oncological and some cardiovascular diseases, diabetes mellitus, osteoporosis, serious dermatological problems, and oncological diseases. It is strongly not recommended to carry out this procedure for those who suffer from renal or hepatic insufficiency because cavitation puts stress on these organs. The presence of pacemakers and any metal implants in the body also precludes this procedure. Pregnant and breastfeeding women should refrain from cavitation too.
