Introduction

In the world of our bodies' intricate systems, Chiari-Frommel Syndrome (CFS) reveals a surprising twist - where hormones are meant to help us bring trouble.^1,2,3,4 Chiari-Frommel Syndrome, also known as Galactorrhea-Amenorrhea Syndrome, is a rare endocrine disorder affecting women after they give birth.^1,2,3,4

This syndrome is characterised by a constellation of symptoms that can persist for more than months or even years after childbirth.^1,2 These women can suffer from amenorrhea (a lack of menstrual periods), backaches, headaches or, in rare cases, impaired vision.^1,2,3,4 Let's delve into the details of this condition and shed light on its causes, symptoms and treatment.

Understanding Chiari-Frommel syndrome

If you are pregnant or have given birth, you might be aware of the changes to a woman’s body after giving birth. These changes include lactation (to allow you to feed your baby) and amenorrhea (​​the lack of menstrual periods), which ensures you don’t fall pregnant until your body is ready to go through pregnancy again.^1,2

These changes typically persist for around six months after childbirth.^1,2 However, they can last much longer than is healthy and negatively affect the body in many ways.^1,2,3,4 In a nutshell, that is what happens in mothers with Chiari-Frommel Syndrome.^1,2,3,4

Now that we have grasped the basic concept of CFS, let us look at how it affects the body. 

Signs & symptoms: what to look for 

Chiari-Frommel Syndrome has some unique signs that can help us recognise it. Let's learn about the things that might happen if someone has this syndrome.

Milk mystery

Even if a mum isn't breastfeeding a baby, or if the little one is past the breastfeeding stage, the breasts might still make milk^1,2,3,4 - like the body is confused. This is not normal, and it's called "galactorrhea".^1,2,3,4

Missing periods and eggs

Another sign of Chiari-Frommel Syndrome is the disappearance of menstrual periods.^1,2,3,4 In Chiari-Frommel Syndrome, menstrual periods don't happen normally - meaning that the eggs needed to make babies are not released from the ovaries as normal.^1,2,3,4 

Hormones, hormones, and more hormones

The hormonal imbalances associated with CFS can cause various symptoms, including feeling very sad or worried a lot, headaches, backaches, stomach pain, weight gain, and even trouble seeing clearly. Some or all of these symptoms might show up.^1,2,3

Uterine atrophy

Chiari-Frommel Syndrome doesn't only change how someone feels, but it can also affect the inside of the body. The muscles in the uterus might get weaker, and the uterus itself can become smaller.^1,2,3,4 This is because it’s not receiving the hormonal signals it usually gets that tell it to grow.^1,2,3,4

What these symptoms mean

If someone has these symptoms, they may have Chiari-Frommel Syndrome - and should talk to a doctor. Although this is a rare condition, the doctor can help figure out what's going on and what can be done to help.

The causes of Chiari-Frommel syndrome 

Chiari-Frommel Syndrome is a puzzle, and we're still trying to figure out why it happens. Let's explore what might be causing this and how it works inside the body.

Tiny tumours and hormones

Sometimes, CFS can be caused by a tiny lump (or tumour) on the pituitary gland, which regulates many of our hormones.^1,2,3,4 These tumours are called microadenomas. Before you get too worried, these tumours are usually benign, or in other words, not cancerous. However, they can be dangerous if left untreated. In these cases, these tumours can cause the brain to produce excessive amounts of the hormone prolactin, and ultimately send the wrong signals to the body.^1,2,3,4 

The body naturally makes prolactin after giving birth, and the hormone is responsible for many of the previously mentioned changes to a woman’s body after birth.^2,3,4 As such, prolactin is responsible for milk production, lactation, amenorrhea, and anovulation (lack of releasing eggs).^1,2,3,4 Mothers typically experience these prolactin-induced effects for around six months after birth.^2,3,4

A prolactinoma (tumour that induces excessive prolactin production) can cause these effects to persist beyond the standard period of six months, and/or make them stronger than they should be. Too much prolactin can lead to women making too much milk, missing periods, experiencing uterine atrophy, and experiencing the other symptoms we discussed above.^1,2,3,4 

But don't forget, only a subset of people with Chiari-Frommel Syndrome will develop microadenomas.^1,2,3,4 There are other reasons for high levels of prolactin in the blood in women with CFS, although these remain unclear.^1,2 Furthermore, not all women with CFS have high levels of prolactin.¹ The following paragraph talks about the proposed reason for these high levels of prolactin and other causes of CFS. 

Confusion in the brain

Microadenoma is only sometimes the cause of Chiari-Frommel Syndrome.^1,2,3,4 Most of the time, the cause is not completely clear - but it is likely to do with the hypothalamus and the pituitary gland.^1,2 Consider the brain as the boss that tells the body what to do.

In Chiari-Frommel Syndrome, the boss might get a bit confused. Two important parts of the brain are involved in CFS – the hypothalamus and the pituitary gland.^1,2,3,4 These parts communicate and help make important hormones, such as prolactin.^1,2,3,4 Chiari-Frommel Syndrome is most likely the result of abnormal or miscommunication between the hypothalamus and the pituitary gland.^1,2

These miscommunications “confuse” the boss and lead it to tell the body to do things it shouldn’t. This can trigger a chain of events that trigger the development of Chiari-Frommel syndrome.^1,2

Diagnosis and medical evaluation 

When doctors suspect CFS due to symptoms like excessive milk production or absent periods, they turn to various diagnostic methods to uncover the underlying causes.^1,2 Below is a summary of the various tools they use to make or exclude CFS. When all the information has been gathered, the doctor can better understand what’s causing the changes in the body and make a final diagnosis.

Talking and listening

When a person goes to the doctor with these concerns and/or changes, the doctor will ask questions and listen carefully to their answers. This includes questions about periods, breastfeeding, and how the body feels. All of this information helps the doctor understand what's happening in the patient’s body - and is the most crucial part of making a diagnosis of CFS. Therefore, it's really important to talk to the doctor and be honest about your symptoms. By working together, the doctor can decide what further investigations are necessary. 

Blood and urine tests 

Doctors will most likely use blood and urine tests that measure the levels of the different hormones present in your body - most importantly prolactin.^1,2 These tests may also look at the level of other hormones, like estrogen and gonadotrophins, in your urine.^1,2,3,4 Based on your specific case and symptoms, the doctor may add other tests to rule out other potential diagnoses. 

Medical pictures (MRI and CT) 

If there are raised levels of prolactin in the blood, (which does not happen in everyone with CFS), doctors may use specialised imaging techniques to get a clear picture of the pituitary gland.^1,2 These techniques make it possible to see possible microadenomas or any other growths on the pituitary gland or elsewhere in the brain.²

Magnetic resonance imaging (MRI)

An MRI machine is a powerful tool that uses a strong magnetic field and radio waves to create detailed images of the brain. When suspecting Chiari-Frommel Syndrome, doctors might use an MRI machine to closely examine the pituitary gland which, as described above, has an important role in regulating our hormones, including prolactin.^1,2

Computed tomography (CT) scan

CT scans combine X-ray technology with advanced computer processing to produce cross-sectional images of the body. While less commonly used for diagnosing Chiari-Frommel Syndrome, CT scans can also provide insights into the structure of the brain and the pituitary gland.^1,2

Watching and waiting

Sometimes, the body fixes itself over time.^1,2 As such, the doctor might keep an eye on things and make sure everything is getting better.

Managing Chiari-Frommel syndrome: treatment approaches and strategies

Medical intervention can play a pivotal role when addressing Chiari-Frommel Syndrome and its associated hormonal imbalances.^1,2 Let's explore the treatment methods and strategies doctors employ to help individuals with this syndrome regain hormonal balance and alleviate its symptoms.

Medications to restore hormonal balance

One of the primary strategies in managing Chiari-Frommel Syndrome involves using medications. These medications target specific hormonal imbalances at the syndrome's core. For example, bromocriptine works by reducing prolactin levels and reducing the size of microadenomas.^1,2 By doing that, bromocriptine helps regulate milk production and restore regular menstrual periods.^1,2

Surgery

Surgery is an option for some women with CFS, butonly when the following conditions are met: a microadenoma is present, is relatively large, and is in a favourable position for surgery.²

Regular monitoring and adjustment

As treatment progresses, doctors closely monitor the individual's response to medications. Regular check-ups and follow-up appointments allow the medical team to assess how well the treatment works and determine whether any adjustments are needed. These adjustments may include changing the dosage of the medication to achieve optimal results. Doctors may also perform further imaging studies (such as MRIs and CTs) and hormonal tests to ensure treatment regimes are working effectively.

Lifestyle and supportive measures

In tandem with medical treatment, individuals with Chiari-Frommel syndrome might benefit from adopting stress management techniques. A supportive environment, including family, friends, and support groups, can offer emotional encouragement and help alleviate the psychological burden that often accompanies hormonal imbalances.

Spontaneous remission and long-term outlook

Luckily, Chiari-Frommel Syndrome can resolve spontaneously, meaning it fixes itself.^1,2,3,4 Spontaneous remission occurs in 40% of people with CFS within five years.³ 

This means the symptoms might improve - and hormonal balance might be restored - without intensive medical intervention.

Summary

Chiari-Frommel Syndrome, also called Galactorrhea-Amenorrhea Syndrome, appears after giving birth and can make life a bit tricky- bringing changes like unexpected milk production, missing periods, and other strange feelings.^1,2,3,4 It’s important to know that doctors can help.

They use tests, imaging studies, and careful listening to understand what's happening.^1,2 They may find tiny bumps in your brain, or that your hormones have become confused - and whilst some people's bodies might fix it on their own, others may need help.^1,2,3,4

Doctors have particular medicines to restore the body's balance of hormones that are appropriate for some people with CFS.^1,2 Getting better is a team effort - and there are a range of support services and groups available for individuals with Chiari-Frommel Syndrome to help them through this journey.
