Erectile Dysfunction (symptoms,signs,causes and treatment options) Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex. Having erection trouble from time to time isn't necessarily a cause for concern. If erectile dysfunction is an ongoing issue, however, it can cause stress, affect your self-confidence and contribute to relationship problems. Problems getting or keeping an erection can also be a sign of an underlying health condition that needs treatment and a risk factor for heart disease. If you're concerned about erectile dysfunction, talk to your doctor — even if you're embarrassed. Sometimes, treating an underlying condition is enough to reverse erectile dysfunction. In other cases, medications or other direct treatments might be needed. Symptoms of Erectile Dysfunction Erectile dysfunction symptoms might include persistent: Trouble getting an erection Trouble keeping an erection Reduced sexual desire Causes of Erectile Dysfunction Male sexual arousal is a complex process that involves the brain, hormones, emotions, nerves, muscles and blood vessels. Erectile dysfunction can result from a problem with any of these. Likewise, stress and mental health concerns can cause or worsen erectile dysfunction. Sometimes a combination of physical and psychological issues causes erectile dysfunction. For instance, a minor physical condition that slows your sexual response might cause anxiety about maintaining an erection. The resulting anxiety can lead to or worsen erectile dysfunction. Physical causes of erectile dysfunction In many cases, erectile dysfunction is caused by something physical. Common causes include: Heart disease Clogged blood vessels (atherosclerosis) High cholesterol High blood pressure Diabetes Obesity Metabolic syndrome — a condition involving increased blood pressure, high insulin levels, body fat around the waist and high cholesterol Parkinson's disease Multiple sclerosis Certain prescription medications Tobacco use Peyronie's disease — development of scar tissue inside the penis Alcoholism and other forms of substance abuse Sleep disorders Treatments for prostate cancer or enlarged prostate Surgeries or injuries that affect the pelvic area or spinal cord Low testosterone Psychological causes of erectile dysfunction The brain plays a key role in triggering the series of physical events that cause an erection, starting with feelings of sexual excitement. A number of things can interfere with sexual feelings and cause or worsen erectile dysfunction. These include: Depression, anxiety or other mental health conditions Stress Relationship problems due to stress, poor communication or other concerns Risk factors As you get older, erections might take longer to develop and might not be a ... https://www.youtube.com/watch?v=L8XOlmPKK0k

What is cancer and types of cancer Cancer refers to any one of a large number of diseases characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissue. Cancer often has the ability to spread throughout your body. Cancer is the second-leading cause of death in the world. But survival rates are improving for many types of cancer, thanks to improvements in cancer screening and cancer treatment in. Symptoms Signs and symptoms caused by cancer will vary depending on what part of the body is affected. Some general signs and symptoms associated with, but not specific to, cancer, include: Fatigue Lump or area of thickening that can be felt under the skin Weight changes, including unintended loss or gain Skin changes, such as yellowing, darkening or redness of the skin, sores that won't heal, or changes to existing moles Changes in bowel or bladder habits Persistent cough or trouble breathing Difficulty swallowing Hoarseness Persistent indigestion or discomfort after eating Persistent, unexplained muscle or joint pain Persistent, unexplained fevers or night sweats Unexplained bleeding or bruising Causes Cancer is caused by changes (mutations) to the DNA within cells. The DNA inside a cell is packaged into a large number of individual genes, each of which contains a set of instructions telling the cell what functions to perform, as well as how to grow and divide. Errors in the instructions can cause the cell to stop its normal function and may allow a cell to become cancerous. What do gene mutations A gene mutation can instruct a healthy cell to: Allow rapid growth. A gene mutation can tell a cell to grow and divide more rapidly. This creates many new cells that all have that same mutation. Fail to stop uncontrolled cell growth. Normal cells know when to stop growing so that you have just the right number of each type of cell. Cancer cells lose the controls (tumor suppressor genes) that tell them when to stop growing. A mutation in a tumor suppressor gene allows cancer cells to continue growing and accumulating. Make mistakes when repairing DNA errors. DNA repair genes look for errors in a cell's DNA and make corrections. A mutation in a DNA repair gene may mean that other errors aren't corrected, leading cells to become cancerous. These mutations are the most common ones found in cancer. But many other gene mutations can contribute to causing cancer. What causes gene mutations? Gene mutations can occur for several reasons, for instance: Gene mutations you're born with. You may be born with a genetic mutation that you inherited from your parents. This type of mutation accounts for a small percentage of cancers. Gene mutations that occur after birth. Most gene mutations ... https://www.youtube.com/watch?v=Y-DBKQKy2uM
