What is a menstrual disorder?
A menstrual disorder occurs when the length, regularity, or process of the menstrual cycle changes significantly. For example, periods may occur more or less frequently, stop altogether, or intermenstrual bleeding and spotting may occur.
Menstrual disorders can generally occur at any stage of life. Irregular cycles are particularly common at the beginning of the reproductive phase and in the years leading up to menopause, when the hormonal control of the cycle changes.
Typical signs of a menstrual disorder
A cycle does not have to last exactly 28 days to be considered normal. Cycles between approximately 21 and 35 days can be within the normal range for adult women, especially if they occur regularly.
Common cycle changes include:
- significantly shortened or prolonged cycles
- strongly fluctuating cycle lengths
- unusually heavy or light bleeding
- absence of menstrual bleeding
- intermenstrual bleeding or spotting
Severe menstrual pain should also be medically evaluated, especially if it is new or significantly affects daily life.
A cycle calendar or a cycle app can help document cycle lengths and bleeding and identify changes over several months.
When is a medical evaluation recommended?
A medical evaluation is advisable if cycle changes occur repeatedly, persist over several months, or are new and clearly pronounced. This applies in particular if menstrual bleeding is absent, cycle lengths fluctuate significantly, intermenstrual bleeding occurs, or menstrual bleeding is unusually heavy or associated with severe pain.
For those wishing to have children, early evaluation can be useful, as irregular or absent cycles may indicate that ovulation is not occurring regularly. Even if menstruation stops for a long time after discontinuing hormonal contraception or if the cycle remains permanently irregular, the cause should be investigated.
Causes of menstrual disorders
Changes to the uterus or cervix can lead to bleeding disorders.
Possible causes include:
- Fibroids
- Polyps
- Changes to the cervix
- Adenomyosis
- Changes or inflammation of the uterine lining
- rarely also cell changes or malignant diseases
These changes can, for example, lead to heavier or prolonged menstrual bleeding as well as intermenstrual bleeding or spotting.
Hormonal causes
Menstrual disorders often arise from changes in the hormonal regulation of follicle maturation and ovulation.
Possible causes include:
- PCOS (Polycystic Ovary Syndrome): One of the most common hormonal causes of menstrual disorders. Ovulation often occurs irregularly or not at all. As a result, cycles can be significantly prolonged or menstrual bleeding may stop altogether for a long period.
- Hypothalamic cycle disorders: Stress, intensive exercise, being underweight, weight loss, or insufficient energy intake can impair the hormonal control of the cycle. This can cause ovulation and menstrual bleeding to become irregular or stop altogether.
- Elevated prolactin levels: Hyperprolactinemia can impair follicle maturation and ovulation.
- Thyroid dysfunction: Both an underactive and an overactive thyroid can influence the menstrual cycle.
- Perimenopause: In the years before menopause, ovulation becomes increasingly irregular, and cycle length and bleeding intensity can change.
- Premature Ovarian Insufficiency (POI): A significantly reduced function of the ovaries before the age of 40 can lead to irregular or absent menstrual periods.
Intermenstrual bleeding or spotting can also be hormonally related. The timing of the bleeding can provide clues, but alone it does not allow for a reliable statement about an estrogen or progesterone deficiency.
How we investigate menstrual disorders
The evaluation of menstrual disorders is carried out in a structured and individual manner. The goal is to identify possible causes and assess how follicle maturation, ovulation, and hormonal regulation of the cycle are functioning. Based on this, we work with you to develop a treatment tailored to the cause, your symptoms, and a potential desire to have children.
-
Initial Consultation
We discuss your previous cycle history, existing symptoms, previous illnesses, and medications. A current or future desire to have children is also important for further diagnostics and treatment.

Gynecological Examination & Ultrasound
Using ultrasound, we assess the uterus, uterine lining, and ovaries, looking for possible organic causes of the cycle or bleeding disorder.
-
Hormone Analysis & Cycle Monitoring
Depending on the specific issue, we determine the hormones relevant to the cycle. In the case of menstrual disorders, it can also be useful to examine the cycle over time: with ultrasound checks and accompanying hormone analyses, we track follicle maturation, ovulation, and the buildup of the uterine lining. This allows us to identify at which point in the cycle abnormalities occur – for example, whether follicle maturation is proceeding correctly, whether ovulation is taking place, and whether the hormonal changes match the respective cycle phases. This allows possible causes of the menstrual disorder to be categorized more specifically and the treatment to be planned accordingly.
-
Medical Assessment
After completing the examinations, we evaluate all findings in context and discuss the results in detail with you. This allows us to classify the possible cause of your menstrual disorder and, on this basis, plan the next steps and an individually suitable treatment.
Medical Evaluation of Menstrual Disorders
Menstrual disorders can have very different causes – from hormonal changes such as PCOS or a hypothalamic cycle disorder to organic changes. Therefore, it is important not only to look at the bleeding itself but to closely examine the cycle and its hormonal regulation.
The underlying cause is decisive for the treatment. Not every menstrual disorder needs to be treated, and not every one requires hormonal therapy. Especially when wishing to have children, it is important to know whether follicle maturation and ovulation are occurring regularly.
Treatment of Menstrual Disorders
If stress, intensive physical activity, being underweight, weight changes, or insufficient energy intake affect the cycle, targeted lifestyle changes can be an important part of the treatment. Depending on the cause, selected herbal preparations may also be considered. We will discuss which measures make sense with you individually.
Depending on the cause, targeted hormonal treatment may be advisable. Which hormones are used and for what purpose depends on the respective menstrual disorder, your symptoms, and whether there is a current desire to have children. Underlying hormonal diseases, such as thyroid issues or elevated prolactin levels, are also treated specifically.
If ovulation does not occur or occurs only irregularly when wishing to have children, medication-based stimulation can specifically support follicle maturation. Depending on the cause and initial situation, Letrozole, a so-called aromatase inhibitor in tablet form, or stimulation with the follicle-stimulating hormone FSH may be considered.
With ultrasound and hormone monitoring, we track follicle maturation and determine the optimal time for ovulation. If necessary, this can be triggered with medication. In this way, the treatment can be controlled individually and the optimal time for sexual intercourse or insemination can be determined.

What Our Patients Say
Frequently Asked Questions about Menstrual Disorders
What is considered a normal cycle?
A cycle does not have to last exactly 28 days. For adult women, cycle lengths between approximately 21 and 35 days are usually considered normal, especially if the cycles occur regularly. Individual deviations are not unusual. However, significant or recurring changes should be medically evaluated.
Do menstrual disorders always require treatment?
No. Not every menstrual disorder needs to be treated. In certain phases of life – such as puberty, during breastfeeding, or in perimenopause – irregular or absent bleeding is not unusual. Stress, illness, heavy physical exertion, or weight changes can also temporarily affect the cycle. Whether treatment is necessary depends on the cause, the symptoms, and a potential desire to have children.
Can menstrual disorders normalize on their own?
Yes. Temporary cycle changes can normalize again, for example after stress, an illness, or temporary changes in weight or physical exertion. However, if menstrual bleeding stops, if the cycles are significantly irregular over a long period, or if additional symptoms occur, the cause should be investigated.
Do menstrual disorders affect fertility?
Yes. Menstrual disorders can affect fertility, but they do not have to. A decisive factor is, in particular, whether follicle maturation and ovulation occur regularly. With very irregular or absent ovulation, it can be more difficult to get pregnant. Targeted diagnostics can often determine the underlying cause and which treatment is advisable when wishing to have children.
What role do hormones play in menstrual disorders?
Hormones control follicle maturation, ovulation, and the buildup of the uterine lining. Changes in this hormonal regulation can therefore lead to prolonged or irregular cycles, absent ovulation, or bleeding disorders. Possible causes include PCOS, elevated prolactin levels, thyroid dysfunction, a hypothalamic cycle disorder, or hormonal changes in perimenopause.
Can stress permanently affect the cycle?
Yes. Severe or prolonged stress can affect the hormonal control of the cycle. Especially in combination with high physical exertion, weight loss, or insufficient energy intake, follicle maturation can be disturbed and ovulation can occur irregularly or stop altogether.
Why is my period missing?
The absence of menstrual bleeding can have many causes. In addition to pregnancy, possible causes include PCOS, a hypothalamic cycle disorder, elevated prolactin levels, thyroid disease, significant weight changes, or impaired ovarian function. If the period is absent for a long time, the cause should be medically evaluated.
What does a very long or irregular cycle mean?
Very long or strongly fluctuating cycles can indicate that follicle maturation is delayed or that ovulation is not occurring regularly. Common causes include PCOS, hypothalamic cycle disorders, or hormonal changes in perimenopause. The cycle can be assessed more precisely with ultrasound and targeted hormone analyses.
When should I see a doctor for menstrual disorders?
A medical evaluation is advisable if cycle changes persist for several months, menstruation is repeatedly absent, intermenstrual bleeding occurs, or there is a desire to have children. Severe pain or very heavy bleeding should also be examined gynecologically. For those wishing to have children, early evaluation can be useful, especially if the cycles are very irregular or ovulation may be absent.
