For many, pregnancy nausea is just a rough morning. For those battling hyperemesis gravidarum, however, it’s a relentless storm that lasts all day, every day. This condition goes far beyond morning sickness, and it can leave women exhausted, dehydrated and emotionally drained. Hyperemesis gravidarum is often misunderstood, dismissed as exaggeration or weakness, when in reality it’s a serious medical condition that can turn pregnancy into survival mode. It deserves compassion, awareness and better support for those enduring it.

Because raising tiny humans is hard work but with the right team (that’s us!), it gets a whole lot easier.
Morning sickness is considered a normal part of early pregnancy. Nausea, food aversions and occasional vomiting are so common that many women see them as a rite of passage. However, when the sickness becomes relentless, when you can’t keep even water down and when you lose weight instead of gaining it, that’s not ordinary morning sickness; that’s Hyperemesis Gravidarum (HG). This is a serious medical condition that can turn pregnancy into a daily struggle for survival.
It’s time to stop brushing it off as “just bad morning sickness” and start understanding what really happens when nausea becomes debilitating.
What Is Hyperemesis Gravidarum?
Hyperemesis Gravidarum is a severe form of pregnancy-related nausea and vomiting that affects about 1 to 3 per cent of pregnant women. Unlike typical morning sickness, which usually eases after the first trimester, HG can last for months, sometimes the entire pregnancy.
It can lead to dehydration, electrolyte imbalances, rapid weight loss, and exhaustion. Some women lose more than 5% of their pre-pregnancy body weight, and the condition can be so severe that it requires hospitalisation for IV fluids or medication.
The condition is caused by a complex mix of hormonal changes, particularly high levels of human chorionic gonadotropin (hCG) and oestrogen, though genetics and gut sensitivity may also play a role. If your mother or sister had HG, you’re more likely to experience it too.
Morning Sickness vs. Hyperemesis Gravidarum
Many people think HG is simply a more intense version of morning sickness, but the two are very different in both severity and impact.
| Feature | Morning Sickness | Hyperemesis Gravidarum |
|---|---|---|
| Frequency of vomiting | Occasionally | Multiple times a day |
| Ability to eat and drink | Can usually keep some food down | Often cannot keep even water down |
| Weight change | Minimal | Significant weight loss |
| Dehydration | Rare | Common, often severe |
| Impact on daily life | Manageable | Debilitating |
| Duration | Usually ends by 12–14 weeks | Can last throughout pregnancy |
Hyperemesis is not a sign of weakness or low pain tolerance. It’s a medical condition that can cause physical, emotional and psychological distress.

The Emotional Toll of HG
The physical symptoms of HG are obvious, but the emotional impact is often overlooked. Imagine waking up every day feeling violently ill, unable to eat, smell food or stand for long periods. The constant nausea makes you dread each hour.
Many women describe the condition as isolating and frightening. Every day tasks become impossible, relationships are strained, and guilt creeps in because you’re not enjoying pregnancy the way others seem to. You may even feel resentful, trapped or disconnected from the experience of becoming a mother.
It’s common to experience anxiety or depression as a result of HG. The unpredictability and intensity of the illness can wear down even the strongest person. That’s why emotional support is just as important as medical treatment.

When to See a Doctor
If nausea and vomiting are interfering with your ability to eat, drink or function, you should speak to your healthcare provider immediately.
Seek medical help if you:
- Can’t keep fluids or food down for more than 24 hours
- Notice dark urine or urinate less than three times a day
- Feel dizzy, faint, or extremely weak
- Experience rapid weight loss
- Have a racing heartbeat or constant dehydration symptoms
Doctors can diagnose HG through physical exams, urine tests (to check for ketones) and blood tests for electrolyte levels.
In South Africa, both public and private hospitals can treat Hyperemesis Gravidarum, and you should never feel guilty for seeking care. Admission for IV fluids, anti-nausea medication and monitoring is standard when dehydration becomes dangerous.
Treatment Options for Hyperemesis Gravidarum
Treatment depends on the severity of your symptoms, but it often includes a combination of medical, nutritional and emotional support.
1. Rehydration
If you’re dehydrated, you’ll likely receive IV fluids in the hospital to restore balance. Electrolytes such as sodium and potassium are also replaced to stabilise your body.
2. Medication
Safe anti-nausea and acid-reducing medications can help. These may include:
- Metoclopramide or ondansetron for nausea
- Vitamin B6 supplements
- Corticosteroids for severe cases
Although these are considered safe, your doctor will choose the safest options based on your pregnancy stage and health profile.
3. Nutritional Support
If you can’t eat or drink enough, you may need nutritional therapy through a feeding tube or IV nutrition. It’s not common, but it can be lifesaving when weight loss becomes dangerous.
4. Rest and Stress Management
HG often worsens with exhaustion and stress. Bed rest, gentle movement when possible, and emotional support can make a huge difference.
5. Emotional and Psychological Care
Therapy or counselling can help you cope with feelings of guilt, fear or isolation. Support groups like the Hyperemesis Gravidarum Foundation of South Africa or international online communities can connect you with others who understand what you’re going through.
What Not to Say to Someone With HG
People often mean well but say things that make the experience harder. If you’re supporting someone with HG, avoid comments like:
- “At least it means your baby is healthy.”
- “Just try eating crackers or ginger.”
- “I had morning sickness too; it’ll pass.”
- “You should be grateful you’re pregnant.”
These statements minimise what the person is going through. Instead, offer practical help like bringing fluids, doing a grocery run or simply listening without judgement.

The Long-Term Outlook
For most women, symptoms ease by the second trimester, though some continue to experience nausea until delivery. After birth, recovery is usually swift once hormone levels stabilise.
However, it’s common to feel anxious about future pregnancies, especially if you’ve had HG before. Talk to your healthcare provider early next time; preventative treatment can start before symptoms worsen.
If you experienced trauma or depression due to HG, therapy can help you process those emotions and rebuild confidence in your body.
Final Thoughts
Hyperemesis Gravidarum is not “bad morning sickness”, it’s a serious condition that deserves medical attention, compassion and support. No one should have to suffer in silence or feel dismissed by outdated myths about pregnancy.
If you’re experiencing HG, know that you are doing an extraordinary job under impossible circumstances. You’re not weak, you’re not overreacting, and you’re certainly not alone.
Seek help, rest when you can, and accept support from those around you. You are already showing immense strength, and that strength is what motherhood is truly built on.
FAQs: Hyperemesis Gravidarum Isn’t Just “Bad Morning Sickness”
When does Hyperemesis Gravidarum usually start?
It typically begins between weeks 4 and 10 of pregnancy and can last much longer than morning sickness, sometimes until mid-pregnancy or even throughout the entire term.
What causes Hyperemesis Gravidarum?
The exact cause is unknown, but it’s thought to be linked to hormonal changes (like high levels of hCG or oestrogen), genetic factors, and possibly gut and immune system responses. Women who’ve had HG before are at higher risk in future pregnancies.
How is Hyperemesis Gravidarum diagnosed?
Doctors diagnose HG based on symptoms, physical examination, and tests like urine ketones, electrolyte levels and weight monitoring to assess dehydration and nutritional status.
Can HG harm my baby?
If treated promptly, most babies develop normally. However, untreated HG can lead to nutritional deficiencies and low birth weight, so medical supervision is essential.
What can I do at home to manage symptoms?
- Eat small, frequent meals and avoid triggers like strong smells
- Sip fluids throughout the day
- Try ginger, lemon, or cold foods if tolerable
- Rest as much as possible
- Ask loved ones for help with cooking and chores
Does Hyperemesis Gravidarum go away after birth?
Yes. Symptoms typically disappear soon after delivery, though recovery can take a few weeks as your body rehydrates and regains strength.
