8 Side Effects of Menstrual Cup That You Should Know About!

Menstrual cups have been around since the late 1930s. But, earlier periods were considered a maligned act and it never got popular in India. The idea of period cups revolted people.

Menstrual Cups are an eco-friendly alternative to sanitary pads and tampons. It is inserted into the vagina during menstruation. It collects the menstrual fluid into the cup which prevents leaking onto your clothes.

But, later it becomes popular with working women who can’t frequently use the washroom and with a fear of red patches on pants, the idea of menstrual cups hit out loud. Now while period cups make life easy, they come with their own set of problems. The concerns of insertion and discomfort pull Indian women apart.

So, what are menstrual cup problems? What are the menstrual cup disadvantages? Are there any side effects of menstrual cups? We have answers to all your questions here.

What Is a Menstrual Cup?

A menstrual cup is a reusable female hygiene product used by women during menstruation. You insert a menstrual cup into your vagina to collect period fluids. It is made from rubber or silicone and is shaped like a funnel. The capacity of these cups to hold more blood than other alternatives has prompted women to consider them as a viable substitute for tampons. A cup can be worn for up to 12 hours, depending on your flow.

Is Menstrual Cup Safe?

Menstrual cup dangers are often asked about a lot. However, it is generally not dangerous as long as it's used properly. The use of menstrual cups is no more hazardous than using tampons or any other period products. However, the use of menstrual cups, similarly to tampons, does carry some risks, especially when they are not used correctly.

Menstrual Cup Side Effects

However, as per studies, the following are some menstrual cup disadvantages or potential risks associated with improper use of menstrual cups.

1. Leakage

Like any other female hygiene product, menstrual cups can leak when in use, which usually happens if the cup is overfilled with liquid or if it is not fitted well. Regularly emptying the cup and choosing one that fits well will help reduce leakage since it will form an airtight seal around the vaginal wall, and it won't move too much throughout the day.

2. Irritation

There may be several reasons why you might experience irritation from using menstrual cups, and most of them can be avoided. If the cup was inserted without proper lubrication, the cup was of the wrong size, or the cup wasn't cleaned correctly between uses, those situations can cause discomfort. Often, this can be avoided by applying some water-based lubricant to the outside of the cup. Make sure to carefully read the instructions on the package of the product for detailed information.

3. Injuries and Pain

It is possible for objects inserted into the vagina to cause small injuries or pain. The likelihood of experiencing these issues increases if one inserts the menstrual cup roughly, has long nails, or uses an oversized cup.

4. Allergies and Rashes

An allergic reaction is possible when using any product, and menstrual cups are no exception. Nevertheless, since they are made of medical-grade silicone, they should not cause an allergic reaction with your vagina unless you have an allergy to silicone. Furthermore, different brands of menstrual cups might work better for some women due to the kind of materials they use.

5. Urinary Problems

When you use menstrual cups, you can introduce bacteria to the urinary tract because inserting any object into the vagina can irritate the urethra. However, there are very rare instances when the cup pushes against the urethra, causing it to become blocked, resulting in difficulties urinating.

6. Dislodged or Expelled IUD

Using a menstrual cup after you've had an intrauterine device (IUD) inserted is said to decrease its effectiveness because the cup can pull on the string or become undisturbed, which can cause the IUD to no longer function. However, as per studies, the expulsion of an IUD occurs naturally in roughly one out of twenty people, regardless of whether they use menstrual cups. As per other studies, using menstrual cups doesn't significantly increase your risk of expulsion from your IUD overusing tampons or pads.

7. Infections

A rare but serious complication of the use of menstrual cups is an infection, most often caused by the transfer of bacteria from hands to cups rather than the cups themselves. For instance, infections such as yeast infections and vaginosis can develop due to the presence of bacteria in the vagina and result in a fluctuating pH level. To prevent this, you should wash your hands well with lukewarm water and antibiotic soap before handling the cup. In addition, cups can also spread infection if they are not kept clean. You should wash the cup before and after use with mild liquid soap and water.

8. Toxic Shock Syndrome

Toxic shock syndrome (TSS) is among the most serious and potentially life-threatening bacterial infections resulting from the penetration of Staphylococcus or Streptococcus bacteria (normally present on your nose, mouth, and skin) into the body. Tampons are typically the cause, but menstrual cups can also cause it in very rare cases.
