If you have fur allergy, you respond to allergenic substances that get stuck in the mucous membranes of the eyes, nose or lungs. The substances usually come from the animal’s saliva, urine or sebaceous glands but also fur. Most people who become allergic to fur animals get their first problems in childhood and adolescence.
The allergic disorders often decrease with age. It is not entirely clear why fur allergy starts, but it can be partly hereditary. The environment can also be important.

Pollen allergy, also called hay fever, causes problems such as red, itchy eyes, nasal congestion, repeated sneezing and runny nose. How severe the problems you get depends on how sensitive you are and how much and what types of pollen are in the air.
The pollen season lasts from early spring to late autumn and varies depending on where in the country you live. Prescription drugs can often alleviate the hassle, but not always completely remove them.

Lactose intolerance

When you have lactose intolerance you have a reduced ability to absorb lactose, ie milk sugar from the food. This is because the intestinal mucosa has a lower level of an enzyme, lactate, which is required for the milk sugar to be broken down and taken up by the small intestine. With a lowered level of lactase, milk sugar will instead end up in the large intestine and will be broken down by bacteria, which can cause pain, diarrhea and gas formation.
