The poorly adjusted menstrual cup can cause health complications

Doctors advise women to take care of menstrual glasses, after a user developed temporary renal problems because the cup was misaligned.

The patient, about 30 years old, had been experiencing intermittent pelvic pain and blood in her urine for months, but had not related symptoms to the menstrual cup, which is used to capture the monthly blood flow.

Although extremely rare, a poorly positioned cup inside the vaginal pass can press on other nearby structures, such as ureters, tubes that lead to the bladder, according to the Danish doctors cited in the British Medical Magazine.

It is important to select the appropriate size cup, as well as insert it correctly, doctors have underlined.

The patient recovered complete, but doctors have warned: “The correct positioning, together with the choice of the correct cup shape and size, is important to prevent negative effects on the upper urinary tract.

“Menstrual glasses can be bought and used without clinical advice from a health professional, which emphasizes the importance of detailed and clear patient information material.”

The reusable and sustainable menstrual glasses are an alternative to sanitary pads and tampons.

They are made of silicone or smooth and flexible rubber and, once correctly in their place, they can contain 20 to 30 ml, about two tablespoons, blood.

They can be removed, emptied, washing and reinserting every four to eight hours, depending on the flow.

The different cup models can offer a better adjustment according to the individual.

There are smaller size options, for younger girls and women who have not given birth to a baby, for example.

If you are a virgin, you can still use one.

However, menstrual glasses can be complicated for users for the first time, particularly when it comes to eliminating.

A recent 530 young survey Many reported that they found it difficult to eliminate the menstrual cup in their first attempt, and some said they had to ask for help.

Once inserted in the vagina, menstrual glasses create a suction seal to stop any blood filtration.

When they retire, users are noticed not simply pulling the stem. Instead, insist on the bottom of the cup to break the seal and move it, says the physiotherapist Dr. Kate Lough, a pelvic health expert.

She says that she can bring to women some menstrual cycles to get used to using one, and emphasizing the use of a cup should not hurt.

She told BBC News: “In general, they are a very safe product.

“When it’s correctly, you shouldn’t feel it.”

Menstrual glasses vary in form, size and firmness, so Dr. Lough advises buying to find one that matches their requirements.

If you have recently had a contraceptive coil in its uterus, there is a very small probability It could be evicted, or even eliminate, by suction.

If the threads cannot be located, or a woman thinks that her coil has moved, manufacturers recommend using additional contraception and seeing a health professional to receive advice.

Menstrual discs are similar to cups, but are used higher on the vaginal channel, just below the cervix.
