Heavy, irregular, or unpredictable periods in your 40s are common, but they should not be ignored. Perimenopause is one possible cause, but abnormal uterine bleeding can also be related to fibroids, polyps, thyroid problems, medication effects, pregnancy-related causes, or changes in the uterine lining.
At Women’s Health Group Chicago, Dr. Michael Awad and our clinical team evaluate abnormal bleeding with a focused, efficient approach that may include in-office ultrasound, lab testing, and endometrial assessment when medically appropriate.
What Is Abnormal Uterine Bleeding?
Abnormal uterine bleeding, or AUB, means bleeding that is different from your usual menstrual pattern in timing, amount, or duration.
You may be experiencing abnormal uterine bleeding if you have:
- Periods that are much heavier than usual
- Bleeding that lasts longer than 7 days
- Bleeding or spotting between periods
- Cycles shorter than 21 days or longer than 35 days
- Sudden changes in your established bleeding pattern
- Bleeding after sex
- Any bleeding after menopause
Occasional variation can happen. Persistent, heavy, or new bleeding changes, especially after age 40, should be evaluated.
Why Periods Often Change in Your 40s
A common reason periods change in your 40s is perimenopause, the transition leading up to menopause. During this time, estrogen and progesterone levels can fluctuate, and ovulation may become less predictable.
These changes can cause:
- Irregular cycle timing
- Skipped or delayed periods
- Heavier bleeding
- Longer bleeding episodes
- Spotting between cycles
However, not every bleeding change should be attributed to perimenopause. A proper evaluation helps determine whether the bleeding is hormonal, structural, medication-related, pregnancy-related, or related to the uterine lining.
Other Causes of Heavy or Irregular Bleeding
Several conditions can cause or contribute to abnormal uterine bleeding.
Fibroids
Fibroids are noncancerous growths in the uterus. They can cause heavy bleeding, pelvic pressure, clotting, and prolonged periods.
Endometrial Polyps
Polyps are growths in the lining of the uterus. They may cause spotting, irregular bleeding, or bleeding between periods.
Adenomyosis
Adenomyosis occurs when tissue similar to the uterine lining grows into the muscular wall of the uterus. It can cause heavy, painful periods.
Thyroid Disorders
Both an underactive and overactive thyroid can affect menstrual regularity.
Ovulation Problems
Skipped or irregular ovulation can lead to unpredictable bleeding and heavier shedding of the uterine lining.
Medication or Hormonal Causes
Blood thinners, some hormonal medications, and certain birth control methods can affect bleeding patterns.
Endometrial Hyperplasia or Cancer
Abnormal thickening of the uterine lining can sometimes represent precancerous or cancerous change. This is one reason new or persistent bleeding after age 40 should be evaluated carefully.
Pregnancy-Related Causes
Pregnancy is still possible in the 40s. When medically relevant, pregnancy-related causes must be ruled out, including miscarriage or ectopic pregnancy.
When Should You See an OB/GYN?
Schedule an evaluation if you have:
- A sudden change in your period after age 40
- Bleeding that soaks through pads or tampons quickly
- Bleeding lasting longer than 7 days
- Bleeding between periods
- Bleeding after sex
- Fatigue, dizziness, shortness of breath, or symptoms of anemia
- Pelvic pain or pressure with heavy bleeding
- Any bleeding after menopause
Bleeding after menopause should always be evaluated.
How We Evaluate Abnormal Uterine Bleeding in Our Chicago Office
At Women’s Health Group Chicago, evaluation is based on your age, symptoms, bleeding pattern, medical history, medications, risk factors, and reproductive goals.
A typical evaluation may include:
Pregnancy Testing When Appropriate
For patients who could be pregnant, pregnancy testing is part of the evaluation.
Blood Work
Blood work may include anemia screening. Thyroid testing or hormone testing may be ordered when symptoms or history suggest a need.
In-Office Ultrasound
Ultrasound can evaluate the uterus, uterine lining, fibroids, polyps, ovarian findings, and other structural causes of bleeding.
Endometrial Biopsy When Indicated
An endometrial biopsy samples the uterine lining. This may be recommended for abnormal bleeding at age 45 or older, or earlier when risk factors, persistent bleeding, or failed medical treatment make sampling appropriate.
Hysteroscopy When Needed
Hysteroscopy allows direct visualization inside the uterus and may be used to evaluate or treat polyps, fibroids, or other uterine cavity findings.
Treatment Options for Heavy or Irregular Bleeding
Treatment depends on the cause of bleeding, severity of symptoms, anemia status, ultrasound findings, biopsy results when performed, and whether future pregnancy is desired.
Options may include:
Hormonal IUD
A levonorgestrel-releasing IUD can significantly reduce heavy menstrual bleeding and may also provide contraception.
Progestin or Other Hormonal Therapy
Progestin therapy or combined hormonal therapy may be used in selected patients to regulate bleeding and protect the uterine lining.
Nonhormonal Medication
Some patients may be candidates for nonhormonal treatment, such as tranexamic acid or anti-inflammatory medication, depending on their medical history and bleeding pattern.
Hysteroscopic Polyp or Fibroid Removal
If bleeding is caused by a polyp or certain types of fibroids, hysteroscopic treatment may be recommended.
Endometrial Ablation
Endometrial ablation treats the uterine lining to reduce heavy menstrual bleeding. It is generally considered only for patients who do not want future pregnancy. Pregnancy after ablation can still occur and can be high risk, so contraception is still needed until menopause.
Hysterectomy
For some patients with severe symptoms, large fibroids, failed conservative treatment, or specific pathology, hysterectomy may be discussed. It is not the first step for every patient, but it can be the definitive treatment in selected cases.
In-Office Care on Harlem Avenue
Many evaluations and selected procedures for abnormal uterine bleeding can be performed in-office at our Harlem Avenue location. This may reduce the need for separate imaging appointments, hospital visits, or delays between diagnosis and treatment planning.
Before any procedure, our team verifies insurance coverage and reviews expected patient responsibility so you understand your options before moving forward.

Frequently Asked Questions
What is the most common reason periods change in your 40s?
A common reason is perimenopause-related hormone fluctuation. However, fibroids, polyps, thyroid disorders, ovulation problems, medication effects, and endometrial changes can also cause abnormal bleeding.
Are heavy periods in your 40s normal?
Heavy periods can occur during perimenopause, but bleeding that is very heavy, prolonged, new, or disruptive should be evaluated.
When should I worry about irregular bleeding?
You should schedule an evaluation for bleeding between periods, bleeding after sex, bleeding lasting longer than 7 days, very heavy bleeding, symptoms of anemia, or any bleeding after menopause.
Do I need an endometrial biopsy?
An endometrial biopsy may be recommended if you are 45 or older with abnormal bleeding. It may also be recommended earlier if you have certain risk factors, persistent bleeding, or bleeding that does not improve with treatment.
What tests are used for abnormal uterine bleeding?
Common tests include pregnancy testing when appropriate, blood work for anemia, ultrasound, and sometimes endometrial biopsy or hysteroscopy.
Can abnormal uterine bleeding be treated without surgery?
Yes. Depending on the cause, treatment may include a hormonal IUD, progestin therapy, combined hormonal therapy, tranexamic acid, or anti-inflammatory medication.
Is endometrial ablation the same as birth control?
No. Endometrial ablation is not birth control. Pregnancy can still occur after ablation and may be high risk, so contraception is still needed until menopause.
Do I need to go to the hospital for abnormal bleeding care?
Not always. Many evaluations and selected treatments can be performed in an OB/GYN office, depending on your symptoms, diagnosis, and medical history.
