What Causes Nausea And Vomiting?
gastritis, symptomatic treatment
I have gone through your query and do understand your concern.
Based on the information I feel she has gastritis.
Most cases of gastritis are caused by viruses and requires only symptomatic treatment, consuming contaminated foods or drinks is another common cause.
I would suggest you few measures that will be beneficial.
Take capsule omeprazole 20 mg once daily empty stomach, before breakfast for a week. If the symptoms persist or increases then you can take tab emset (antiemetic). You require valid prescription to get this.
Apart from the medicines--
Avoid spicy and oily food for few days till the symptoms are resolved. Avoid or reduce the intake of meat, dairy products, and add more fiber to your diet. Eat lots of salads, vegetables, fresh fruits.
Avoid excess consumption of tea/ coffee/ hydrogenated drinks. Avoid smoking and alcohol, if any.
Eat frequent small meals instead of heavy ones and do not starve. Do not lie down immediately post food, sit or walk for a while.
Eat light meals prepared under hygienic conditions. Avoid eating fast and talking while eating.
Follow this measures you should be fine.
If you have any further doubt, I'll be glad to help you out.
