This guide shows you when to call your doctor or head to the ER, what help is available, and how to prepare for a visit so you get relief faster.

How to tell if your morning sickness is severe

Most morning sickness is unpleasant but manageable. You might feel nauseated, nibble on crackers, and still make it through your day. Severe morning sickness, however, disrupts daily life and can make it hard to stay hydrated or nourish yourself.

Hyperemesis gravidarum, or HG, is persistent, severe nausea and vomiting in pregnancy. It can cause dehydration and weight loss, and it often requires medical care. It is not your fault, and it does not mean you are doing anything wrong. Timely care matters because ongoing vomiting can upset your electrolytes, lower your blood pressure, and drain your energy. If your symptoms keep you from drinking or you are losing weight, it is time to reach out. Early support can prevent complications and help you feel better sooner.

Call your doctor if you notice these symptoms

• You cannot keep liquids or food down for 24 hours.
• You show signs of dehydration (very dark urine, peeing fewer than 3 times a day, dry mouth, dizziness, fast heartbeat).
• You are losing weight, such as more than 5 pounds or over 5 percent of your pre-pregnancy weight.
• Nausea and vomiting are getting worse after week 12, or last all day, most days.
• You have little relief after trying simple home steps (small, frequent snacks, ginger, rest).

Go to urgent care or the ER for these danger signs

• You cannot keep any fluids down for 24 hours and feel weak or lightheaded.
• You have signs of severe dehydration (very little urine, confusion, fainting, severe headache).
• You see blood in vomit, or vomit looks like coffee grounds.
• You have severe belly pain, fever, or a stiff neck.
• You feel your heart racing or you have chest pain.

If symptoms are severe or rapidly worsening, call 911.

What your doctor can do to help, from diagnosis to treatment

Your provider will start by confirming how severe your symptoms are, then build a plan that fits your needs. They will check for dehydration, look for weight changes, and rule out other causes. Many safe treatments exist in pregnancy when guided by a clinician. Care may include vitamin therapy, anti-nausea medicines, and rehydration. Some people improve with oral options, while others need IV fluids for a short time. The goal is simple, to help you drink, eat small amounts, and reduce vomiting. Most patients feel better with the right mix of steps, plus close follow-up to adjust care if needed.

What to expect at the appointment

• Review of symptoms, what you can keep down, and triggers.
• Weight check and hydration check, urine test for ketones.
• Possible blood work for electrolytes, and sometimes an ultrasound to rule out other causes.
• A plan for follow-up, plus when to call back if symptoms do not improve.

Safe treatments that often work

• Vitamin B6 alone or with doxylamine.
• Prescription anti-nausea medicines when needed (such as ondansetron, metoclopramide, promethazine), guided by your provider.
• IV or oral rehydration, sometimes thiamine if vomiting is prolonged.
• Supportive steps: small frequent snacks, cold bland foods, electrolyte drinks, ginger or acupressure wrist bands, rest.
• Note: your provider balances benefits and risks for you and your baby.

How to prepare and advocate for yourself at your visit

A little prep can speed up care. Set a clear goal, like staying hydrated and cutting vomiting in half within a few days. Bring a brief symptom diary and your questions. Think about what you can tolerate by mouth, for example, ice chips or cold sips. Share your concerns, such as fear of dehydration or weight loss. Ask for a written plan so you know when to step up care. Being direct and detailed helps your provider act fast and tailor treatment.

Bring this simple symptom checklist

• A 3-day log of what you ate or drank and what stayed down.
• Times you vomited, your urine color, and how often you peed.
• Current weight and any recent weight change.
• What you already tried (foods, ginger, wrist bands, medicines) and what helped.
• Your prenatal vitamin brand and any other medications.

Smart questions to ask your provider

• Could this be hyperemesis gravidarum, and how will you monitor me?
• Which medicine should I try first, what dose, and when should I feel better?
• How do I stay hydrated at home, and when should I get IV fluids?
• What are my danger signs and the exact plan if they show up?
• When is my follow-up, and how can I reach you if symptoms get worse?

Conclusion

You deserve care, and severe morning sickness is treatable. Call your doctor if you cannot keep fluids down, are losing weight, or have signs of dehydration. Go to urgent care or the ER for danger signs like fainting, blood in vomit, severe pain, or chest symptoms. The right help, started early, protects you and your baby and brings real relief. You are not alone, and you do not have to tough it out.
