A decidual cast is a rare gynecological condition where the uterine lining sheds in one large piece, often resembling the shape of the uterus. It affects the reproductive system and can cause sudden pelvic pain, heavy bleeding, and discomfort. Early diagnosis and proper management are key to preventing complications and supporting overall reproductive health.

What are the Decidual Cast Symptoms?

A decidual cast can appear suddenly and may feel alarming due to the physical and emotional discomfort it brings. Recognizing the symptoms early can help you seek timely medical support and avoid complications.

Common Symptoms

• Sudden pelvic pain or lower abdominal cramps
• Passage of a large, tissue-like material from the vagina
• Heavy menstrual-like bleeding
• Spotting between periods
• Lower back discomfort

Severe Symptoms

• Intense or unmanageable abdominal pain
• Fainting or dizziness
• Excessive or prolonged bleeding
• Signs of infection like fever or foul-smelling discharge

What are the Common Causes and Risk Factors of Decidual Cast?

A decidual cast occurs when the lining of the uterus sheds in one solid piece, often triggered by hormonal changes. High levels of progesterone followed by a sudden drop can trigger the formation of a decidual cast.

Birth Control

Some types of hormonal birth control, which affects particularly those that contain high levels of progesterone medicine, have been linked to the formation of decidual casts.

The introduction of synthetic hormones can sometimes disrupt the natural hormonal balance, leading to abnormal endometrial shedding.

Pregnancy and Miscarriage

Although less common, decidual casts can occur during pregnancy or after a miscarriage. In these cases, the cast is composed of the decidua, which forms during pregnancy.

Risk Factors and Other Medical Conditions

Certain medical conditions that affect hormonal balance or uterine health can also contribute to the formation of decidual casts.

These include polycystic ovary syndrome (PCOS), endometriosis, and certain types of uterine infections.

Diagnosing a decidual cast involves careful examination to confirm the condition and exclude other issues. At Medicover, we use proven methods combined with expert care to identify the cause accurately.

What are the Treatment Options for Decidual Cast?

Treating a decidual cast mainly involves easing pain, managing symptoms, and preventing it from happening again. The treatment depends on how severe the symptoms are and the cause behind them.

Decidual Cast Treatment Methods

• Pain Relief: Most people find relief with common painkillers like ibuprofen or acetaminophen. If the pain is strong, doctors may prescribe stronger medication to help.
• Hormonal Treatment: Sometimes, adjusting hormone levels through birth control or other medications can help regulate the menstrual cycle and stop future episodes.
• Surgery: In uncommon cases, a simple procedure like dilation and curettage (D & C) is needed to remove the cast and any leftover tissue, especially if pain is intense or complications occur.
• Ongoing Care: Follow-up visits and tests help make sure the problem is under control and that no other issues are causing symptoms.

At Medicover, our doctors listen carefully and create treatment plans that fit each person's needs. We offer experienced care and support through recovery, helping patients feel comfortable and confident every step of the way.

What Is the Recovery Process After Decidual Cast Treatment?
