Severe pregnancy sickness that prevents eating, drinking or daily activity may be hyperemesis gravidarum. Learn dehydration warning signs, how to seek care in India and what assessment and treatment may involve.
In this guide
What is hyperemesis gravidarum?
Nausea and vomiting can happen in pregnancy at any time of day. Hyperemesis gravidarum (HG) is a severe form that can stop someone from eating or drinking normally and make daily life difficult. It can lead to dehydration and weight loss, and it deserves medical care rather than being dismissed as ordinary morning sickness.
Look for signs that fluids or food are not staying down
Contact a clinician promptly if vomiting is frequent, you cannot keep fluids down, you are passing much less urine, urine is very dark, you feel dizzy or unusually drowsy, or you are losing weight. These signs do not prove HG, but they can indicate dehydration or another condition that needs assessment.
Severe pregnancy sickness is not a test of strength
HG is a health condition, not a lack of willpower or a failure to eat the right food. Symptoms can affect sleep, mood, work, caregiving and relationships. Tell the care team how often you vomit and what you can keep down, and ask for help with practical needs.
Other causes may need to be checked
A clinician may look for other causes, especially if vomiting begins later in pregnancy or occurs with abdominal pain, fever, painful urination or other new symptoms. Do not assume every episode of vomiting is HG without assessment.

When should you get medical help?
Do not wait until a scheduled antenatal visit if you cannot keep fluids down or symptoms are stopping normal daily activity. Contact your maternity team, obstetric clinician or hospital for timely advice.
Ask for same-day advice when vomiting is severe
Tell your clinician if you cannot keep drinks down, are urinating much less, have dark urine, feel dizzy or are losing weight. Ask where you should be assessed and how quickly. If you cannot reach your usual clinician, contact a hospital with maternity services.
Use emergency care for collapse or severe new symptoms
Call 112 or go to emergency care if you faint, become confused, are too weak to stand, have severe abdominal pain, blood in vomit or another rapidly worsening symptom. The clinician should also consider causes other than HG when symptoms are unusual.
Ask someone trusted to help with transport and care
If you feel faint or exhausted, do not travel alone if you can avoid it. A supporter can help record symptoms, arrange transport, care for children or communicate with the clinic while keeping your preferences and privacy central.
What assessment and treatment may be offered?
The care team bases treatment on symptoms, hydration, examination and any other health conditions. International RCOG patient information describes options used in UK care; a clinician in India should explain what is available and suitable locally.
Assessment may check hydration and other causes
The team may ask about vomiting, fluid intake, urine, weight and medicines, check vital signs, and order tests when needed. They may assess for another cause if there is pain, urinary symptoms, fever or later onset. Explain any condition or medicine that makes it difficult to take tablets.
Clinicians can discuss pregnancy-appropriate treatment
Depending on the assessment, care may include anti-sickness medicines and fluids given by a route you can manage. Some people need hospital care. Ask about expected benefits, possible side effects, how to take a medicine and what to do if you cannot keep it down; do not use someone else’s prescription.
Agree when to return and how to get support
Ask what improvement should look like, when to return if symptoms persist, and whether weight or the baby’s growth needs follow-up. Discuss mental health, work, food access and caregiving too; treatment should address the impact on the whole person.
Hyperemesis gravidarum: frequently asked questions
Is HG just morning sickness?
No. Ordinary pregnancy nausea can be unpleasant, but HG is severe enough to interfere with eating, drinking or daily activities and may cause dehydration or weight loss. A clinician can assess severity and rule out other causes.
Does HG always stop by a certain week?
No. Symptoms vary. RCOG notes that severe sickness may continue beyond the period when many people improve. If symptoms persist or worsen, contact your care team rather than assuming you must wait it out.
Will HG harm the baby?
Many people with HG do well with effective treatment. Severe or prolonged illness and weight loss can affect pregnancy, so early assessment and follow-up are important. A clinician can discuss your individual situation; a general article cannot predict an outcome.
What if family members say I should tolerate it?
You deserve care when vomiting is affecting hydration, nutrition or daily life. You can show them the symptom log and ask one trusted person to help you contact a clinician. Your symptoms should not be dismissed as a character issue.
