Untreated, it can lead to heart failure, where the heart fails in its action as a pump and the blood is no longer pushed efficiently through the lungs and kidneys. The person becomes short of breath and fluid may be retained in the tissues, leading to oedema (swelling).
High blood pressure may damage the kidneys and lead to their failure and cause secondary effects which push up the pressure even further.
Damage to the arteries from the raised pressure is widespread throughout the body and, in the eye, may lead to impaired vision from small haemorrhages or a clot or thrombosis in the retinal vessels.
Damage to the arteries supplying the brain can cause strokes. Transient ischaemic attacks (TIA) occur when there is spasm or actual blockage of small cerebral arteries. These are like minor strokes but the symptoms do not persist.
A clot in a major brain artery causes a stroke or cerebro-vascular accident (CVA). Partial recovery from the paralysis, which is the main symptom, is usual.

Cow’s milk contains about 14 different proteins, all capable of becoming allergens. Each may be broken down or digested into around 12 different substances and all of these can induce an allergy. This means there are over 100 different combinations in cow’s milk which may induce allergy in susceptible individuals.
The testing of food allergies may be difficult, as the original food may not be the problem but products from it.
Children with allergies to cow’s milk may have recurrent episodes of diarrhoea, sometimes with blood in the motions, or the allergy may result in eczema or even asthma.
If both parents have a history of allergy, there is a strong likelihood their children will be similarly affected. If the infant is to be artifically fed, a substitute for cow’s milk should be considered, at least for the first six months.
Goat’s milk is also capable of causing allergy and, unfortunately, so is soya bean. Plants contain protein, carbohydrate and oils, all of which are capable of being allergens. It is the oil of soya bean which is the main cause of allergy to this food.
