What causes bleeding between periods and what should I do about it?

Symptom Database

Abnormal uterine bleeding, also known as bleeding between periods, irregular menstrual bleeding, intermenstrual bleeding, or spotting between periods, can be a cause of concern for many women. It refers to any bleeding that occurs outside of the regular menstrual cycle. While occasional spotting or light bleeding between periods may not be a cause for alarm, persistent or heavy bleeding can indicate an underlying issue that requires medical attention. In this article, we will explore the possible causes of bleeding between periods and discuss what steps you should take if you experience this symptom.

Understanding the Causes

There are several potential causes of bleeding between periods. It is important to note that while some causes may be benign, others may require medical intervention. Here are some common causes:

Hormonal Imbalances

Fluctuations in hormone levels can disrupt the normal menstrual cycle and lead to irregular bleeding. Hormonal imbalances can occur due to factors such as stress, excessive exercise, weight fluctuations, or certain medical conditions.

Birth Control Methods

Some forms of birth control, such as hormonal contraceptives or intrauterine devices (IUDs), can cause spotting or irregular bleeding as a side effect. This is particularly common during the first few months of using a new contraceptive method.

Infections or Sexually Transmitted Diseases (STDs)

Infections in the reproductive organs, such as pelvic inflammatory disease (PID) or sexually transmitted diseases (STDs), can cause abnormal bleeding. These infections often come with other symptoms like pain, itching, or unusual discharge.

Uterine Fibroids or Polyps

Fibroids are noncancerous growths that can develop in the uterus, while polyps are small, benign growths that can occur in the lining of the uterus. Both fibroids and polyps can cause irregular bleeding between periods.

Endometriosis

Endometriosis is a condition in which the tissue that normally lines the uterus grows outside of it. This can lead to heavy or irregular bleeding, as well as pelvic pain.

When to Seek Medical Attention

While occasional spotting between periods may not be a cause for concern, it is important to pay attention to any changes in your menstrual cycle. If you experience any of the following, it is advisable to seek medical attention:

  • Heavy bleeding that requires changing pads or tampons every hour for several hours
  • Bleeding that lasts longer than a week
  • Bleeding after menopause
  • Bleeding accompanied by severe pain or other concerning symptoms

It is always better to consult a healthcare professional to determine the underlying cause of the abnormal bleeding and receive appropriate treatment.

Diagnosis and Treatment

When you visit a healthcare provider for abnormal uterine bleeding, they will likely perform a thorough evaluation to determine the cause. This may involve:

  • Reviewing your medical history and menstrual cycle patterns
  • Performing a physical examination, including a pelvic exam
  • Ordering blood tests to check hormone levels
  • Scheduling imaging tests, such as an ultrasound or MRI, to visualize the reproductive organs
  • Performing a biopsy to examine the uterine lining

The treatment for bleeding between periods depends on the underlying cause. Some common treatment options include:

  • Hormonal therapy to regulate hormone levels
  • Antibiotics to treat infections
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) to manage pain and inflammation
  • Surgical interventions, such as removing fibroids or polyps
  • Endometrial ablation or hysterectomy in severe cases

It is important to follow your healthcare provider’s recommendations and attend regular follow-up appointments to monitor your condition.

Conclusion

Bleeding between periods can be a distressing symptom, but it is essential to remember that it can have various causes, ranging from hormonal imbalances to underlying medical conditions. If you experience abnormal uterine bleeding, it is crucial to consult a healthcare professional for an accurate diagnosis and appropriate treatment. Early intervention can help address any underlying issues and ensure your reproductive health. Remember, your healthcare provider is the best resource for guidance and support in managing this symptom.
