1. What is internal uterine bleeding?

It is bleeding that occurs inside the uterus, outside the regular menstrual periods or in larger amounts than normal. Sometimes, it can happen without obvious external bleeding.

2. What causes internal uterine bleeding?

There are many causes, the most common include:

Hormonal imbalances affecting the menstrual cycle regularity.
Presence of fibroids inside the uterus.
Infections of the uterine lining (endometritis).
Blood clotting disorders.
Pregnancy itself can sometimes cause bleeding.
Sometimes, serious causes like cancer tumors.

3. Can internal uterine bleeding be dangerous?

Yes, it can be dangerous if the bleeding is heavy, persistent for a long time, or accompanied by severe pain, fever, or if it occurs after menopause. In these cases, you should see a doctor immediately.

4. How is internal uterine bleeding diagnosed?

The doctor starts with a clinical examination, then may request:

Ultrasound (sonography) to check the condition of the uterus.
Blood tests to check hormone levels and blood counts.
In some cases, a biopsy (sample) of the uterine lining for examination.

5. What are the treatment methods for internal uterine bleeding?

Treatment depends on the cause, for example:

Hormonal medications if the cause is hormonal imbalance.
Antibiotics if the cause is infection.
Surgical intervention if there are tumors or other problems.
Monitoring pregnancy if bleeding is related to pregnancy.

6. Can internal bleeding occur during pregnancy?

Yes, and in this case, you must follow up with your doctor quickly because bleeding can be a sign of complications like miscarriage or ectopic pregnancy, which need urgent treatment.

7. Can internal uterine bleeding affect fertility?

In some cases, especially if caused by fibroids or repeated infections, bleeding can affect the chances of pregnancy if not treated promptly.

8. When should you see a doctor because of uterine bleeding?

If you notice heavy or continuous bleeding, bleeding after complete menopause, or bleeding accompanied by severe pain or other symptoms like fever, you must see a doctor immediately.

9. Can internal uterine bleeding be prevented?

Yes, you can prevent it by maintaining hormonal balance, regular pregnancy checkups, promptly treating any infections, avoiding smoking, and steering clear of harmful medications.

10. Can internal uterine bleeding be a sign of cancer?

It can be, especially for women over 40 years old or after menopause, which is why early medical checkup is very important.

11. Can an IUD cause internal uterine bleeding?

Sometimes, an IUD can cause light bleeding or spotting, especially in the first few months after insertion, which is normal. But if it continues, you should consult your doctor.

12. Do weight and nutrition affect uterine bleeding?

Definitely! Sudden weight gain or rapid loss affects hormone balance, which can cause abnormal bleeding.

13. Can stress and psychological pressure cause uterine bleeding?

Yes, stress changes hormone levels in the body, which can lead to irregular periods or abnormal bleeding.

14. Can uterine bleeding be treated with herbs?

Some herbs may help, but you must consult your doctor before using them to avoid complications or drug interactions.

15. How to differentiate between regular menstrual bleeding and internal uterine bleeding?

Menstrual bleeding is regular with a certain pattern, whereas internal bleeding is irregular, can occur between periods, or in larger quantities than normal.

When is uterine bleeding dangerous? Warning signs you should never ignore!

Not all uterine bleeding is dangerous, but some cases require immediate action and doctor consultation because delay can lead to serious complications. Here are the main signs that uterine bleeding is dangerous:

Very heavy bleeding
If the blood loss is so much that you feel severe weakness, dizziness, or even fainting, it might indicate severe anemia and needs urgent medical intervention.
Bleeding that lasts a long time
If bleeding continues for more than 7 days or happens repeatedly without an obvious cause, it may indicate hormonal imbalance or uterine problems.
Bleeding after menopause
Any bleeding after menopause is a serious warning because it might be linked to major problems like tumors or uterine cancer.
Bleeding with severe pain
If bleeding is accompanied by strong abdominal or pelvic pain, it could be caused by ectopic pregnancy, cysts, or severe infections, requiring immediate examination.
Bleeding with other worrying symptoms such as:

Fever
Difficulty breathing
Rapid heartbeat
General weakness or unusual fatigue
These signs may indicate internal bleeding or serious uterine infection.

Bleeding after childbirth or surgery
Especially if it is sudden and heavy, it might be due to uterine problems or retained placental tissue, requiring urgent care.
Bleeding in cases of blood clotting disorders
If you have clotting problems or take blood-thinning medications and the bleeding increases, contact your doctor immediately to prevent complications.

What are the causes of internal uterine bleeding?

Internal uterine bleeding can worry any woman and happens due to many causes, some simple and temporary, others serious. Let’s look at the main causes of abnormal uterine bleeding:

Hormonal disorders
Any imbalance in estrogen and progesterone hormones can cause irregular uterine lining shedding, leading to sudden or continuous bleeding.
Uterine fibroids
These are benign tumors inside or around the uterine muscle that can cause heavy bleeding or pain during periods.
Endometritis (uterine lining infections)
When the uterine lining is inflamed, the body reacts with abnormal bleeding, sometimes accompanied by pain or fever.
Polyps
Small growths in the uterine or cervical lining that cause bleeding between periods.
Pregnancy and its complications
Bleeding can be due to ectopic pregnancy or early miscarriage, requiring quick medical intervention.
Physical or psychological stress
Severe stress, lack of sleep, or intense physical pressure can disrupt the cycle and cause abnormal bleeding.
Certain medications
Hormonal contraceptives or blood thinners (like warfarin) can cause cycle changes or sudden bleeding.
Thyroid problems
Thyroid gland controls hormones; hypo- or hyperthyroidism can cause irregular bleeding.
Cancer
Rarely, bleeding can indicate uterine or cervical cancer, especially in women over 40 or postmenopausal.
Breastfeeding
Some mothers experience mild bleeding during breastfeeding due to hormonal fluctuations.
Endometriosis
When uterine lining grows outside the uterus (ovaries, fallopian tubes), it can cause heavy bleeding and pain, especially during periods.
Ovulation
Some women experience light bleeding during ovulation (mid-cycle), which is normal and harmless.
Stress and anxiety
Psychological factors can disrupt hormone levels causing irregular or abnormal bleeding.
Uterine injury
After surgeries, curettage, or IUD insertion, irritation of the uterine lining can cause bleeding.
Blood clotting disorders
Conditions like hemophilia or blood thinning medication use increase bleeding tendency even from minor causes.
Infections
Vaginal or uterine infections (bacterial or viral) can cause bleeding, often with itching or abnormal discharge.
Bleeding during menopause
If bleeding occurs after menstrual cessation, see a doctor because it may indicate uterine or cervical problems.
Other cancers
Such as ovarian, uterine, or cervical cancer, usually accompanied by persistent pain or unexplained weight loss.

Types of Internal Uterine Bleeding

Uterine bleeding isn’t just one type — it varies depending on timing, amount, and cause. Here are the main types of internal uterine bleeding:

Abnormal Uterine Bleeding (AUB)
Any bleeding that differs from a normal menstrual cycle in timing, amount, or duration.
Heavy Menstrual Bleeding (Menorrhagia)
Very heavy or prolonged menstrual periods, which can cause anemia and general fatigue.
Intermenstrual Bleeding (Metrorrhagia)
Light bleeding or spotting between periods, often due to hormonal issues or benign tumors.
Postmenopausal Bleeding
Bleeding after menopause is a serious warning sign that may indicate uterine problems or tumors, requiring urgent medical evaluation.
Hormonal Bleeding
Occurs when there is an imbalance in estrogen and progesterone levels, affecting cycle regularity and causing bleeding.
Bleeding Due to Fibroids or Polyps
Fibroids or polyps in the uterus can cause repeated or heavy bleeding.
Pregnancy-Related Bleeding
Bleeding in early pregnancy, miscarriage, or ectopic pregnancy, requiring immediate medical attention.
Bleeding Caused by Infections or Injuries
Infections of the uterus or vagina, or internal injury from exams or rough intercourse can cause bleeding.
Ovulatory Dysfunction Bleeding
If ovulation is irregular or absent, hormonal imbalance may cause abnormal bleeding.
Medication-Induced Bleeding (Iatrogenic)
Some medications, like hormonal contraceptives or blood thinners, can cause bleeding side effects, especially early in use.
Acute and Sudden Bleeding
Sudden heavy bleeding that may cause shock and requires emergency care.
Chronic Bleeding
Light but persistent or recurrent bleeding over months, often disturbing quality of life.
Bleeding Due to Clotting Disorders
Conditions like Von Willebrand disease or use of blood thinners can make bleeding easier and more severe.
Bleeding From Cancerous Tumors
Uterine, cervical, or ovarian cancers can cause abnormal bleeding, mostly in women over 40 or postmenopausal.
Bleeding from Tears or Injuries
Such as after childbirth or cervical tears during exams or surgery.

Symptoms of Internal Uterine Bleeding

Internal uterine bleeding may not always be obvious but can appear through various physical and psychological symptoms depending on severity and cause:

Abnormal Vaginal Bleeding

Diagnosing Internal Uterine Bleeding: Step by Step

Medical History and Physical Exam
The doctor will ask about:
- When the bleeding started and its pattern
- How much and how long it lasts
- Accompanying symptoms like pain, dizziness, fever, or discharge
  Then a pelvic exam will check the uterus, cervix, and ovaries.
Blood Tests
These help detect general or hormonal problems:
- Complete Blood Count (CBC) to check for anemia
- Hormone levels (estrogen, progesterone, thyroid hormone TSH)
Ultrasound (Sonography)
A safe, painless method to:
- Visualize uterus and ovaries
- Detect fibroids, cysts, or thickening of the uterine lining
  Can be abdominal or transvaginal ultrasound.
Hysteroscopy
If ultrasound is insufficient, a thin scope is inserted via the vagina and cervix to:
- Directly view the inside of the uterus
- Take a biopsy sample from the uterine lining if needed
Endometrial Biopsy
Important when there is suspicion of:
- Chronic inflammation or abnormal cell changes
- Possible tumors or precancerous cells
  The sample is examined under a microscope.
Advanced Imaging (Sonohysterography or MRI)
For more detailed evaluation:
- Sonohysterography: saline is injected into the uterus during ultrasound for clearer images
- MRI: used for complex cases like tumors or suspected uterine cancer

When to See a Doctor Immediately?

Go to the doctor urgently if you experience:

Sudden very heavy bleeding
Dizziness or fainting
Severe pelvic pain
Bleeding after menopause

Treatment of Internal Uterine Bleeding: Based on Cause and Condition

Treatment varies between women depending on the cause, age, and health status. It generally divides into:

Medical Treatment: Hormonal therapy, medication to control bleeding, iron supplements for anemia.
Surgical Treatment: Removal of fibroids, polyps, or abnormal tissue; procedures like endometrial ablation or hysterectomy in severe cases.

First: Medical Treatment (Non-Surgical)

Hormonal Regulation
If the cause is hormonal, the doctor may prescribe medications to regulate the cycle and reduce bleeding, such as:

Combined oral contraceptive pills: Regulate hormones, reduce bleeding, and make periods more regular.
Progesterone: Useful if there is a weak uterine lining or hormonal imbalance.
Hormone Replacement Therapy (HRT): For women after menopause.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)
Such as ibuprofen or naproxen, these reduce inflammation and pain, and can also reduce the amount of bleeding during periods.
Antifibrinolytic Medications
Such as Tranexamic Acid, which helps the body maintain blood clots and prevent them from breaking down, thereby significantly reducing bleeding.
Antibiotics
If bleeding is caused by infection or inflammation in the uterus, the doctor will prescribe appropriate antibiotics.
Medications for Special Conditions
In some cases, such as Polycystic Ovary Syndrome (PCOS), doctors may prescribe medications like Metformin to help regulate hormones.

Second: Surgical Treatment (For Advanced Cases)

Removal of Fibroids or Polyps (Myomectomy or Polypectomy)
If bleeding is caused by fibroids or uterine polyps, they are surgically removed, usually by minimally invasive laparoscopic surgery for quicker recovery.
Dilation and Curettage (D&C)
A simple procedure to clean the uterine lining from excess or damaged tissue, which helps stop bleeding and regulate the cycle.
Endometrial Ablation
Partial or complete destruction of the uterine lining using special tools. It’s very effective for chronic bleeding but not suitable for women who wish to become pregnant.
Hysterectomy (Complete Removal of the Uterus)
A last resort for severe cases or cancer, this procedure permanently stops bleeding but also ends fertility.

Is Surgery Always Necessary?

No. Most cases are treated medically first, and surgery is reserved for:

When medications fail to control bleeding
Presence of large tumors
Suspicion of cancer
Persistent bleeding affecting overall health

Conservative Management of Uterine Bleeding: When to Monitor Instead of Intervene?

Not all uterine bleeding needs medication or surgery. Many cases are mild or temporary, so doctors may choose conservative management if:

Bleeding is light or irregular
General health is good
Cause is not serious or chronic

Conservative care includes:

Monitoring menstrual patterns: Track cycle timing, bleeding amount, and symptoms.
Regular blood tests: To monitor iron levels and anemia.
Periodic medical check-ups: To ensure the condition is stable without worsening.

Lifestyle Modifications: More Powerful Than You Think

Rest and stress reduction
Stress affects hormones and may increase or trigger bleeding. Practice relaxation techniques such as yoga or deep breathing.
Regular exercise
Light exercises like walking or swimming help balance hormones and improve circulation, reducing abnormal bleeding risks.
Maintain a healthy weight
Both excess and low weight disrupt hormones and increase bleeding risk. Aim for a balanced, healthy lifestyle.
Avoid smoking and alcohol
These negatively affect uterine and vascular health and may worsen bleeding.

Proper Nutrition: Your Shield Against Anemia

Increase iron-rich foods such as liver, spinach, black molasses, and lentils to prevent anemia caused by bleeding.
Ensure adequate intake of vitamins D and B12 for efficient body function and hormonal health.

Managing Chronic Diseases Associated with Uterine Bleeding

Sometimes bleeding stems from chronic illnesses affecting hormones or blood clotting. Proper treatment and follow-up are critical.

Thyroid disorders
Both hypothyroidism and hyperthyroidism can cause irregular or heavy bleeding. Proper treatment improves symptoms significantly.
Diabetes
Affects blood vessels and uterine lining, causing bleeding problems. Controlling blood sugar helps reduce bleeding.
Blood clotting disorders
Inherited or acquired conditions impair clotting, leading to excessive bleeding. Diagnosis and specialist care are necessary, including medications to improve clotting.
Other chronic conditions (e.g., hypertension, liver disease)
These can worsen bleeding severity or delay its stoppage. Managing these diseases helps prevent serious bleeding episodes.

Important Advice for Managing Chronic Conditions

Follow your doctor’s treatment plan strictly.
Report any changes in bleeding or unusual symptoms immediately.
Maintain a healthy, balanced lifestyle to support your body’s management of these conditions.

Treating Special Cases of Uterine Bleeding: When Is Bleeding a Danger Sign?

Some uterine bleeding cases stem from serious health issues and require urgent, specialized treatment.

Bleeding during pregnancy
Bleeding is not normal and may indicate serious problems such as:

Early miscarriage: Bleeding early in pregnancy, especially with pain or tissue passage, needs urgent medical assessment.
Ectopic pregnancy: Implantation outside the uterus (often fallopian tube), causing bleeding and severe pain, is a medical emergency.
Placental problems: Placenta previa or placental abruption can cause bleeding in the second or third trimester, needing close monitoring or early delivery.

Bleeding related to blood diseases
Conditions like hemophilia or thrombocytopenia cause frequent or heavy bleeding. Treatment may include clotting factor replacement, blood transfusions, and specialist follow-up.
Bleeding due to cancer
Sudden or persistent unexplained bleeding may be a symptom of cervical or endometrial cancer. Diagnosis involves biopsies and imaging, followed by treatments like surgery, chemotherapy, or radiation. Early detection greatly improves outcomes.
Postmenopausal bleeding
Any bleeding after menopause, even a single drop, is abnormal and requires prompt evaluation for hormonal changes or possible cancer.
Medication-induced bleeding
Some drugs cause bleeding as a side effect, such as:

Blood thinners (warfarin, aspirin)
Hormonal medications (contraceptives, HRT)
If bleeding starts after new medication, inform your doctor for dose adjustment or change.
