Allergy Symptoms Checker – Nausea and vomiting

Nausea

A queasy, grumbling or lurching sensation in the stomach, with the feeling that you might vomit, is characteristic of nausea.  It is often accompanied by clammy skin and a feeling of light-headedness, and may actually lead to vomiting. As with other symptoms and signs of a food allergy or intolerance, nausea can have many other causes, including early pregnancy, emotional stress, head injury and food poisoning [1].  A symptom and allergy tracking app like AlliApp would be extremely advantageous if you experience nausea after eating but are not 100% sure what may be causing it, especially if you have sought medical advice, but still have no solid diagnosis.

 

Vomiting

Vomiting is the voluntary or involuntary forcible expulsion of the stomach contents through the mouth.  Similarly to nausea, there are several other conditions that can cause vomiting [1]. When caused by a food allergy or intolerance, it is a protective response by your immune system to something it perceives as a threat.  The immune system releases a substance called histamine, which can trigger both vomiting and nausea, along with other reactions associated with a food allergy or intolerance [2]. Histamine can be released in various parts of the body in response to ingesting an allergen (food or drink that causes an allergic or intolerance reaction) including the mouth, brain, stomach or intestines.

Tracking potential causes

Using a tracking app to record your meals may be of great benefit if you often feel nauseous or actually vomit after eating, and have no idea what the underlying cause is.  Having adverse reactions to food can have a huge impact on your life. Social occasions such as parties or simply eating out become fraught with stress and anxiety. When investigating potential food allergies or intolerances, sufferers are always advised to keep a food diary.  Downloading a tracking app like AlliApp onto your phone is a much more convenient way to do this. You can always have it close to hand wherever you are, ready to record what you have eaten. The inbuilt camera also allows you to photograph your meals, together with any visible symptoms that accompany your nausea or vomiting, such as hives or other rashes.  After recording your meals for at least 7 days, the app will analyse which foods are most likely causing your symptoms. You can then take this information to your healthcare provider.
