Pregnancy Hormones and Link with Mental Health

Pregnancy is a transformative experience filled with joy and exhilaration. However, it can be physically and emotionally taxing on the mother’s body. During pregnancy, hormonal fluctuations occur and can manifest positively or negatively on a mother’s mental health. These hormonal changes may lead to or exacerbate mental health conditions and can occur before, during or after the pregnancy. Understanding these hormonal changes is crucial to understanding their impact on a mother’s mental health. 

Pregnancy Hormones  

Drastic hormonal changes can have a toll on the mother’s emotional well-being. This includes changes in hormones such as progesterone, estrogen and oxytocin. 

1. Progesterone  

Progesterone is thought to help in regulating our mood and anxiety. During pregnancy, progesterone levels progressively rise but decreases sharply after delivery. This sudden decline results in a drop in mood, increasing the risk of postpartum depression. 

2. Estrogen  

Like progesterone, estrogen levels increase steadily and then sharply decline after birth. It affects body functions including brain function and works together with serotonin to impact an individual’s mood. Its sudden decline could also increase the risk of postpartum depression. 

3. Oxytocin  

However, not all hormonal changes have negative impacts. Oxytocin, also known as the “love hormone” increases in its production during pregnancy. This promotes stress and anxiety relief.  

The intensity of hormonal changes varies by individuals. Factors such as a history of mental health issues, lack of social support, trauma and biological predispositions can increase the risks of experiencing poor mental health during pregnancy.  

 Effects of hormonal changes during pregnancy are more common than you think, with up to 40% of mothers in Singapore reporting feelings anxiety or depression. Therefore, it is important to be aware of the signs and symptoms of these maternal mental health conditions to tackle the symptoms before they escalate. 


Symptoms of Declining Mental Health 

Maternal mental health refers to the social, emotional and mental well-being of a mother during pregnancy or postpartum. These hormonal changes, if left untreated, can result in maternal mental health disorders such as perinatal anxiety, perinatal depression, post-traumatic stress disorder or bipolar affective disorder. Therefore, it is crucial to understand some of the symptoms and warning signs of pregnancy related mental health disorders.

Symptoms of perinatal anxiety and depression include:  

  • General or persistent worrying  

  • Feelings of irritability, frustration, or restlessness 

  • Changes in appetite  

  • Difficulty sleeping, waking early in the morning, or oversleeping 

  • Withdrawing from friends or family  

  • Diminished interest or enjoyment in activities  

  • Feelings of worthlessness, guilt or helplessness 


Building Mental Resilience During Pregnancy 

Apart from understanding how hormonal changes in pregnancy can affect our mental health, there are also active steps we can take to build our mental resilience. Mental wellness strategies include: 

  • Engaging in regular exercise  

Moving your body promotes the release of endorphins also known as “happy” hormones that naturally boost your mood and relieve feelings of stress.  

  • Maintain a support network  

Surrounding yourself with people you love and trust, such as your partner, family, friends or pregnancy support groups can provide emotional comfort and practical help. You do not have to struggle alone. 

  • Get into a routine  

When your mind feels out of control, maintaining a sense of structure in your life can be reassuring. Setting regular sleep, meal and relaxation times can create a sense of control and reduce feelings of anxiety in your life. 

  • Eat a balanced diet 

Did you know that what you eat can also affect your mood? Ensuring you consume a well-balanced diet rich in all the essential vitamins and nutrients is crucial in promoting healthy brain function and mood regulation. 

  • Practice mindfulness and relaxation techniques 

Engaging in mindfulness and relaxation techniques (e.g. 4-7-8 breathing) can help manage anxiety and promote feelings of calm, even in moments of stress.  

However, if emotional distress during pregnancy affects daily functioning or persists for an extended period, it is crucial to seek guidance from a mental health professional.  

Hormonal changes play a significant role in shaping a mother’s mental health and the overall pregnancy experience. Thus, understanding the connection between hormones and mental health is essential for fostering self-awareness and reducing stigma. By engaging in self-care strategies and seeking professional care when required, you are equipped to thrive in your pregnancy journey. 

Understanding Disordered Eating and Mental Health

Misconceptions of Disordered Eating

Wait! Disordered eating or eating disorder? Aren’t they the same?

Not exactly! While they share some similarities, they are different.

An “eating disorder” is a clinical diagnosis, with specific criteria for conditions like anorexia or bulimia.

On the other hand, “disordered eating” refers to unhealthy eating behaviours or patterns that don’t meet the full criteria for an eating disorder.

Someone with disordered eating may not have an eating disorder, but people with eating disorders often exhibit disordered eating behaviours. Disordered eating is quite common and can often go unnoticed, as it may show up in small actions you might do daily without realising.


How do I know if I have disordered eating and not an eating disorder?

While there is no single, perfect guideline on what constitutes “normal eating” as each of our bodies is different, healthy eating is about nourishing our body in a balanced and flexible way. Not overly restrictive, preoccupied, or obsessed (binging, excessive calorie counting).

The golden rule: eat when hungry and stop when satiated (not when you’re about to unbutton your pants).

Whether it’s 3 regular meals a day, or smaller portions but more frequently, our food intake should have all the necessary nutrients our body needs.

In contrast, disordered eating can fly under the radar because its signs are usually more subtle. In contrast, eating disorders are generally more severe and easier to spot. For more information, read more about eating disorders here.

But when it comes to disordered eating, here are a few behaviours to take note of:

Ψ     Eating when stressed or for comfort
Ψ     Eating when not hungry or not for nourishment
Ψ     Following restrictive diets
Ψ     Fasting for extended periods (more than 24 hours)
Ψ     Regularly skipping meals
Ψ     Episodes of binge eating
Ψ     Using diet pills to control weight
Ψ     Misusing diuretics, laxatives, or enemas
Ψ     Feeling guilty after eating or for eating certain foods

If any of these sound familiar, it may be time to reflect on our relationship with food.

Here’s a short summary of the differences between disordered eating and eating disorders:

Disordered Eating

Eating Disorders

Eating for emotional reasons

Frequently thinking about food

Eating to cope with distress

Extreme calorie concern

Rigid rituals or routines around food and exercise

Fixation on weight and body shape

Occasional calorie restriction or bingeing

Disruption in daily life

Selective eating

Significant weight changes


Disordered Eating and Mental Health: The Connection

While disordered eating might seem less severe than an eating disorder, it can still impact both physical and mental health over time.

Disordered eating often stems from emotional reasons, particularly to cope with distress. This distress may come from feeling heightened stress in our lives, or anxiety about our weight, health or appearance.

For example, finding ourselves rummaging through the office pantry right after lunch because we’re feeling stressed or skipping dinner because we’re already full from snacks, telling ourselves, "I need to lose weight.”

Soon after, feelings of regret and guilt may arise, whether from eating or restricting food. This can lead to anxiety, low self-esteem, or feeling unsatisfied, prompting behaviours like skipping meals or overeating. This cycle of stress, eating, guilt and restriction can create a pattern that’s hard to break.

If you notice the signs, it might be time to check in on your emotional needs.

Okay, I think... I might have it. So, what should I do now to stop it?

The key is to start from within. Addressing disordered eating isn't just about changing eating habits – it's also about understanding the emotional and mental factors that drive these behaviours. Here are some steps you can take:

Ψ    Gather knowledge and check in with yourself often

Start by learning the signs of disordered eating and eating disorders, just like you’re doing now! Recognising these patterns early can help you catch them before they become more ingrained.

Mindfulness plays a big role here. Stay grounded and present and be aware of your emotions and physical cues. Eat when you’re hungry and try to differentiate between physical hunger and emotional hunger.  

Ψ    Try alternative coping mechanisms

If you’re using food to deal with emotions like stress or sadness, or even binge eating when you’re feeling happy, try adopting healthier ways to manage your emotions and eating, such as:

  • Exercise: Physical activity can help relieve stress and improve mood.

  • Creative hobbies: Engage in activities like painting, writing, or crafting to channel your emotions in a productive way.

  • Heathy snacks: Opt for nutritious options like fruits.  

Ψ    Avoid fad diets

Fad diets often promise quick results but can harm your body and disrupt healthy eating habits.

Focused on balanced, long-term changes (choosing healthier options, or preparing your own meals) instead of drastic restrictions that can lead to disordered eating behaviours.

Ψ    Self-positive encouragement

Celebrate small victories! Even the tiniest steps toward healthier behaviours, deserve recognition. Use positive self-talk to motivate yourself. You could say things like:

  • “Good job to me! I didn’t overeat, even though I loved the food!”

  • “I made it! I didn’t skip any meals this week!”

Sometimes, enjoying a good meal can be a form of celebration – just remember to enjoy it in the right portion and be aware of when you feel satiated. 

Okay, but what is the right portion?
There’s a Chinese saying, “qi (7) fen bao, gang gang hao,” which means “eat until you’re 70% full.” This could be the balanced portion your body needs.

Ψ    Set realistic goals

Don’t expect to change everything overnight. Set achievable, small goals that focus on improving your relationship with food and your body. This could be as simple as:

  • Eating 3 regular meals per day

  • Reducing emotional eating from 5 times a week to 3 times

Lastly, if you’re struggling to manage disordered eating on your own, reaching out for professional support is a great next step. Therapists, dietitians, or counsellors specialised in eating behaviours can guide you toward healthier coping strategies and a balanced relationship with food.
