Leptin is a hormone that helps manage appetite levels. If you are feeling lethargic or if you want to lose a little bit of weight, you may require more leptin in your system. Leptin works by informing your brain about how much you have in your fat reserves.
For most cases of food poisoning, symptoms tend to come on within one to three days of eating the contaminated food. However, for some types of food poisoning, this 'incubation period' can be as long as 90 days.
Food poisoning is a common illness. It is usually mild, but can become severe and in some cases fatal. Symptoms of food poisoning (such as nausea, vomiting, abdominal cramping, and diarrhoea) may start suddenly (within 48 hours) of having contaminated food or drink, or may be as late as 70 days. These symptoms are affected by many factors including type of contaminant, the amount eaten, age and your overall health.
