Usually when you eat to comfort yourself you go for junk foods like ice cream, chocolate, confectionery and other foods that aren’t nutritious. And while eating comfort foods is not a problem if consumed in moderation, when you’re eating these foods frequently then this can cause nausea.
If you’re binge eating, where you eat excessive amounts and then purge, you may have an eating disorder. The nausea associated with eating disorders is usually linked to over eating. When you’re excessively full you stretch your stomach and it can cause discomfort.

Stomach flu and the nausea linked to food poisoning are often caused by poor hygiene in the kitchen. Unwashed hands, food and incorrectly prepared foods are the most common causes. Other causes of food poisoning are not refrigerating foods, undercooked meat, raw proteins and cross-contaminated foods.
Most cases of food poisoning are treatable at home and will be resolved within 3 to 5 days. However, it is crucial that you drink plenty of water, avoid caffeine and eat foods such as bananas, rice and toast. Flat lemonade and drinks that restore electrolytes like sports drinks can assist in faster recovery.

If you don’t think you can improve your nutrition by yourself, then seek out professional advice. A nutritionist, dietician or other specialist can help you understand your eating patterns. They can also assist you to design an eating plan to suit your dietary needs and body type.

Signs that you are allergic to foods are an upset stomach, nausea, vomiting and even dizziness.
Ignoring these signs can cause you serious harm. Therefore, it’s essential to seek professional help. A doctor will help you control your symptoms and they may even refer you to a specialist for further treatment.
Often a specialist will try to find out which food is triggering your reaction. This diagnosis will then help you to avoid this type of food in the future. As a result, you’ll avoid a reoccurrence of your nausea and other symptoms.
If you start to feel sick after eating certain meals, then cut those foods out of your diet. Keep a food diary to work out how certain foods make you feel. You can then plan and pack meals around those ingredients that don’t make you feel ill.
Some of the most common foods associated with allergies are:
- Milk
- Peanuts
- Shellfish
- Wheat
- Soy
- Nuts
- Eggs
- Fish
