Nausea can occur at any time of the day, but is common in the morning for a variety of reasons. If you experience chronic nausea, schedule an appointment with your doctor to determine the underlying cause. Nausea is a symptom, not a condition, and it indicates a larger problem going on.
The most common reason for morning nausea is early pregnancy; this type of nausea is referred to as "morning sickness." Morning sickness can actually occur all day for pregnant women, as it is the result of a drop in blood sugar. To avoid it, try eating small meals throughout the day, and eat a few crackers or something small before getting out of bed in the morning.
Low blood sugar can cause nausea in the morning for people who are not pregnant as well. When your blood sugar drops after you digest your food, you may feel nauseous. This often occurs in the morning due to the length of time between dinner and waking up. Eat a later snack or an early morning snack before rising to avoid this type of nausea.
The nausea you feel in the morning could actually be acid reflux or indigestion; this is also called GERD (Gastroesophageal Reflux Disease). If you eat just before bed and then lie down, it can be difficult for your body to digest that food, and it may come back up. Try eating an earlier dinner, or staying awake longer after a late-night snack, in order to avoid this.
Morning nausea can be the result of a psychological disorder, such as Generalized Anxiety Disorder, Depression, or Social Anxiety Disorder. The nausea you feel could be the result of feeling anxious or nervous about your day, or a physical reaction to the emotional upset that you feel about your life.
See a Doctor
If your morning nausea worsens, it could be an indicator of a serious illness. See a doctor right away if your nausea is accompanied by severe chest pain or headache, fainting, high fever and stiff neck, or blurred vision. Also seek medical attention if your vomit contains blood or stool, resembles coffee grounds, or is green.
