Healthcare professionals demand that women use caution with menstrual cups since improper usage led to a single reported rare incident of temporary kidney complications. A female patient in her thirties suffered pelvic discomfort together with urinary blood discharge before doctors diagnosed the issue as improper menstrual cup placement. The report in the British Medical Journal revealed that the wrongly inserted cup pressed against the woman’s urine tubes which transport urine to her bladder.
The eco-friendly reusable menstrual cup consists of soft silicone or rubber materials for holding up to 30ml of menstrual blood. Doctors highlight that users must select the proper makeup and placement of a menstrual cup in order to prevent adverse effects. The patient achieved full recovery from her experience which proves that clear instructions about proper sterilization measures need to be communicated because cups can be bought without medical oversight.
Health professionals recommend new users to stay patient because acquiring the proper technique for cup insertion and removal requires about several menstrual cycles. Removing the menstrual cup needs a proper break of suction because discomfort can occur otherwise. Women who use contraceptive coils must exercise due caution with menstrual cups because the suction force might detach their device. 
Dr. Kate Lough from the pelvic health field tells users they will feel no discomfort when using a correctly sized cup which stays discreet inside the body. Users should test various cup sizes and shapes together with firmness rates to determine the optimal fit according to Dr. Kate Lough. Women can maintain menstrual cups as an environmentally friendly solution alongside their ease of use.
