Family history plays an important role in a person’s health condition. For example, if in any family history of cancer, it means that we or our children have the possibility to inherit the same gene. In other words, the risk for developing cancer is much higher than the risk of individuals who do not have the gene.
So far scientists have identified genes that can increase the roughly 400 most prominent disease conditions, such as Parkinson’s and cystic fibrosis or fatal condition caused by genetic mutations. Cystic fribrosis cause the formation of thick, sticky mucus in the lungs and various other parts.
However some diseases are caused not only by a single gene but rather due to a combination of several factors such as diet and lifestyle. Call it like high blood pressure, heart disease or schizophrenia.
Here are some of the diseases and their percentage of the level of risk that may be derived related to a history which is owned by family members:
1. High blood pressure
Hypertension or high blood pressure is a state where a person experiences an increase in blood pressure above normal or chronic (long periods). Hypertension is often not realized because it is not symptomatic. To find the blood pressure measurements were taken. If not promptly treated, may increase the risk of stroke or heart attack.
Inherited risk: According to experts, if one of your parents have high blood pressure, your risk of getting this disease by 15 percent or even higher.
2. High cholesterol
In the same family, sometimes its members have high cholesterol levels. These circumstances in medicine is called Familial Hypercholesterolaemia (FH). FH is caused by changes in the gene where the fat is not metabolized properly in the blood and accumulate in the arteries. FH is one example of a dominant genetic trait, which means that a person needs only one abnormal gene for the condition.
Inherited risk: Dr Nigel Capps said, if one of your parents have familial hypercholesterolemia, then you have a 50 percent risk of getting the disease.
Hypothyroidism occurs when the body does not produce enough of the hormone thyroxine. Symptoms appear usually often feel fatigue and weight loss. The disease is seven times more likely to occur in women.
Inherited risk : Dr. Mark Cohen, a consultant endocrinologist from Spire Bushey Hospital, Hertfordshire revealed, has a brother or a mother with thyroid (underactive), then you have a risk 20 times more likely to get it.
4. Bipolar disorder
Bipolar disorder (also known as manic depression) is a condition that causes periods of depression and mania, is usually triggered by stress. Thought to be caused by chemical imbalances in the brain, and the influence of genetic factors.
Inherited risk: If there are parents who have the disease, the risk for each of their children are experiencing the same thing by 10-15 percent.
Inherited risk: If there is one parent with type 2 diabetes, disease risk was lowered by 15 percent. But if both parents have the condition, disease risk was lowered to 75 percent of their child. However, other factors such as obesity, exercise lazy and unhealthy eating can increase the risk.
6. Arthritis (rheumatoid arthritis)
Osteoarthritis is a type of joint disease that is caused by wear and tear of the joints and is one of the great family of arthritis that most often occur. This disease affects about 80 percent of people at some time in their lives.
Inherited risk: Many people who think that osteoarthritis is an inherited disease. But Dr. Studio said this condition is actually very rare inherited. “This usually occurs because of wear and tear on the joints,” he said.
7. Motor Neuron Disease (MND)
MND is a deadly disease that has been known since the 19th century. Because relatively rare to find a doctor often miss detecting the symptoms of this disease and many were diagnosed as stroke.
The disease generally damage the nervous system, causing muscular weakness. This disease tends to affect people aged over 40 years and more often among men. The exact cause is unclear, but this disease can be lowered.
Inherited risk: Researchers say about 10 percent of these disease can be lowered if you have close relatives with conditions like these.
8. Breast and ovarian cancer
Breast cancer is the most common cancer suffered by women. Breast cancer is one of the biggest causes of disease death in women. While ovarian cancer, commonly known as the “silent killer”, was ranked fifth as a cause of death from cancer in women.
Inherited risk: According to research while 90 percent of cases are not inherited. Only 5-10 percent of breast cancers are caused by mutations of genes inherited from one’s mother or father. BRCA1 and BRCA2 gene mutations are the most frequent. Women with these mutations have an increased risk of developing breast cancer by 80 percent. Increased risk of ovarian cancer also connected with this gene mutation.
Parkinson’s disease begins as a vague and slow to develop. In many patients, initially emerged as Parkinson’s tremors (shaking) hand while resting. This disease tends to run, although sometimes not genetic factors play a major role. “Again, this is a multi-factorial condition,” said Dr Walker.
Inherited risk: According to Walker, those who have parents, siblings or close relatives with Parkinson’s disorder, then twice more likely to experience similar things.
