Morning Sickness and Coffee: Is There a Connection?

Quick answer

• Some people find coffee helps their morning sickness. Others find it makes it worse.
• Caffeine is the main suspect, but it’s not the only factor.
• Dehydration can also play a role. Coffee is a diuretic.
• Listen to your body. What works for one person might not work for you.
• If you’re concerned, talk to your doctor. They can offer personalized advice.

Key terms and definitions

• Morning Sickness: Nausea and vomiting that can occur at any time of day during pregnancy, most commonly in the first trimester.
• Caffeine: A stimulant found in coffee, tea, chocolate, and some sodas.
• Diuretic: A substance that promotes the production of urine. Coffee acts as a mild diuretic.
• Dehydration: A condition where the body loses more fluid than it takes in.
• First Trimester: The first 13 weeks of pregnancy.
• Hormonal Changes: Significant shifts in hormones like hCG and estrogen occur during early pregnancy, often contributing to nausea.
• Blood Sugar Levels: Fluctuations in blood sugar can sometimes trigger or worsen nausea.
• Acid Reflux: Pregnancy can relax the valve between the esophagus and stomach, leading to heartburn and nausea.
• Sensory Sensitivities: Heightened sense of smell during pregnancy can make certain odors, like coffee, unbearable.
• Hydration: The process of maintaining adequate fluid balance in the body.

How it works

• Coffee contains caffeine, a stimulant. For some, this can perk them up and distract from nausea.
• For others, caffeine can irritate the stomach lining. This can increase nausea or trigger vomiting.
• Coffee is a diuretic. This means it can make you pee more.
• If you don’t drink enough water to compensate, you can become dehydrated. Dehydration itself can cause nausea.
• The acidity of coffee can also be an issue for some pregnant individuals. It might worsen heartburn or indigestion.
• The smell of coffee, especially when you’re sensitive, can be a major trigger for nausea.
• Sometimes, it’s not the coffee itself, but the habit of drinking it on an empty stomach that causes problems.
• Pregnancy hormones are the primary driver of morning sickness for most. Coffee can either exacerbate or, in some cases, coincidentally alleviate symptoms.
• Your individual digestive system and how it reacts to different substances is key.

What affects the result

• Caffeine Content: The amount of caffeine in your cup matters. An espresso has less than a large drip coffee.
• Brewing Method: Different methods extract different compounds. Some might be gentler on the stomach.
• Coffee Strength: A strong brew might be more irritating than a weak one.
• Additives: Milk, cream, sugar, or artificial sweeteners can all impact how your stomach reacts. Dairy can be a trigger for some.
• Timing: Drinking coffee on an empty stomach is often a recipe for disaster when pregnant.
• Hydration Levels: If you’re already a bit dehydrated, coffee can make it worse and increase nausea.
• Individual Sensitivity: Everyone’s body is different. What bothers one person might be fine for another.
• Hormonal Fluctuations: Your pregnancy hormones are the main game in town. Coffee is just a player.
• Other Foods Eaten: What else you consume around the same time can influence digestion.
• Overall Diet: A balanced diet supports better digestion.
• Stress Levels: Stress can amplify nausea symptoms.
• How You Feel That Day: Some days are just rougher than others.
