Atrial Fibrillation

Atrial Fibrillation (also referred to as AFib or AF) is a common but debilitating heart disorder that results in an irregular heartbeat, also known as arrhythmia, affecting over 300,000 Canadians with a prevalence of 2.3% adults over the age of 40, and 5.9% of adults over the age of 65. 70% of individuals diagnosed with AFib are between the ages of 65 and 85, with men having an increased incidence than women.

As a physician in Greater Vancouver, Dr. Ali Ghahary is able to treat the aforementioned conditions and symptoms in effort to avoid the development of Atrial Fibrillation and its complications. 




As the risk of being diagnosed with Atrial Fibrillation can increase with age, it is also important to be aware of other risk factors and underlying conditions that can cause this disorder, i.e. high blood pressure, diabetes, hyperthyroidism and sleep apnea. Individuals who have been diagnosed with an underlying heart disease are also at an increased risk of developing AF – such as heart valve problems, previous history of heart attack, congenital heart disease and congenital heart failure, in addition to family history. Those with AF are also five times more likely to have a stroke in comparison to someone without this condition. Complications such as blood clots can also arise, and if traveled through the blood stream can cause a blockage, which can sometimes be fatal.

Those with Atrial Fibrillation may not always experience symptoms. However, manifestations of AFib can include heart palpitations, dizziness, fainting and shortness of breath. If you experience any alarming, sudden symptoms such as chest pain, a feeling of pressure in your chest, or have difficulty breathing, you should seek medical attention immediately by calling 9-1-1.

Patients are almost always referred for further non-invasive testing which may include an electrocardiogram to check the heart’s electrical activity, an echocardiogram to take images of the heart, and a holter test – a portable ECG machine that you wear for several days to closely monitor your heart’s rhythm. Blood tests may also be ordered. Dr. Ali Ghahary may also refer patients to Vancouver’s Atrial Fibrillation Clinic for assessment by a Cardiologist. The Vancouver AFib Clinic is an initiative designed to help educate patients on their condition and improve their quality of life by providing treatment plans, referrals to other services if necessary, and follow-up appointments.

The fundamental objective in treating Atrial Fibrillation is to prevent blood clots from forming. The most commonly prescribed meds to ensure that blood clots do not form is Warfarin and Aspirin. Patients may also require other medications like beta-blockers or calcium channel blockers in effort to stabilize their heart rate. Patients diagnosed with Atrial Fibrillation should also ensure that they are maintaining a diet that is heart-healthy, exercise regularly, and don’t smoke.

Link Between Obesity and Sleep Apnea



Since 1985, rates of obesity in Canada have tripled. It’s a startling trend, and by 2019 as many as 25% of Canadians are expected to be diagnosed as being obese. Causes of obesity range from genetics, physical inactivity, medications, and unhealthy eating habits. Dr. Ali Ghahary, a physician in Vancouver practicing at Brentwood Medical Clinic in Burnaby, has been a long-time advocate of patients leading healthy lifestyles, which includes keeping fit and having diets that are low in carbohydrates. 

Dr. Ali Ghahary personally recommends the Paleo diet or South Beach diet, which are not just focused on weight loss, but instead focus on the patient’s overall health.


There has also been a discovery that shows obesity may be linked to sleep apnea, or vice versa – especially in teenagers, with more than 5% of Canadian teenagers suffering from sleep apnea; that number rises to as many as 60% in teenagers who are obese. 

Sleep apnea is a common condition that affects the airways by causing pauses in breathing, with less air getting to the lungs as a result. This then causes a disruption in sleep. As our quality of sleep is disturbed, one may find it more difficult to control their eating habits, and the want to exercise will also diminish due to feeling overtired. Risks include developing high blood pressure, diabetes, and stroke. This is especially worrisome in younger patients, as developing these problems at an early age can have a significant impact on one’s health. Teenagers that are diagnosed as being obese in addition to having a diagnosis of sleep apnea are also more likely to have trouble concentrating in school or at work, and are at a greater risk of developing mental health issues such as depression and anxiety.

An obvious symptom of sleep apnea is loud snoring with pauses in breathing that can last as long as 20 seconds. Headaches and a constant feeling of fatigue are also two common symptoms in patients, young and old, suffering from sleep apnea. In order to properly diagnose if this is a condition that you or your teenager may have, your doctor may refer you to a sleep clinic (there are several in and around Vancouver.) These Vancouver sleep clinics are specifically designed to determine what sleep disorders, if any, you might have, and can perform specific diagnostic testing such as a sleep study. A sleep study will monitor your breathing, oxygen levels, as well as the number of times you wake up during the night.

Prostate Cancer: A Leading Cancer in Males Across Canada

Dr. Ali Ghahary, a family physician, practices at Brentwood Medical Clinic, a collaborative family practice and walk-in clinic located at Brentwood Town Centre in Burnaby. There, Dr. Ghahary sees patients of all ages – from newborns to elderly, ranging from minor health ailments to more complicated and chronic conditions such as kidney disease and various types of cancer.

One of the leading cancers for male patients across Canada is prostate cancer – the formation of a malignant tumour in the cells of the prostate. The prostate is a walnut-sized gland located just beneath the bladder and surrounding the urethra, which carries urine from the bladder. Prostate cancer typically grows slowly, and if caught early enough can usually be managed quite successfully or even removed completely. On average, an estimated 59 men are diagnosed with prostate cancer each day, with over 21,000 men in Canada being diagnosed this year alone.

Signs and symptoms of prostate cancer to watch out for include changes in bladder habits (i.e. frequent urination, the urgency or inability or urinate, a weak or interrupted urine stream, and burning or pain during urination in addition to blood in the urine.) Late symptoms can also include bone pain, weight loss, anemia, fatigue, and complete loss of bladder control.

In order to diagnose prostate cancer your physician may examine you in order to check for any hard bumps that may have the possibility of being cancerous. In addition, patients will also be referred for diagnostic testing. A common screening test to check for prostate cancer is a PSA test, otherwise known as a Prostate-Specific Antigen test. This test is performed by drawing blood and checking your PSA levels. Typically, most men who are healthy will have a PSA level under 4ng/ml. However, with an increased PSA level the risk of having prostate cancer also increases significantly. With a PSA level over 10, that risk grows by 50%. Another common test used to diagnose prostate cancer is a core needle biopsy. This is usually done depending on the patient’s symptoms and results of other tests, such as the PSA blood test. It is important to note that even with a PSA level below 4, that does not necessarily mean you are 100% cancer-free, as 15% of male patients are found to have prostate cancer after a biopsy has been performed. Treatment for prostate cancer may include surgery, chemotherapy and radiation – all of which are performed as either standalone treatment or in combination.

There are many prostate cancer support services in and around Vancouver, including the Prostate Cancer Foundation of BC, located in Surrey. Their goal is to provide knowledge and help to individuals diagnosed with prostate cancer, in addition to raising funds in support of further research and treatment options. In order to raise funds and bring awareness to the fight against prostate cancer, they hold an annual fundraiser every summer – the Father’s Day Walk/Run for Prostate Cancer. This run takes place across various cities in British Columbia including Metro Vancouver, Chilliwack, Kamloops and Kelowna.

Anatomy of the Ear and Common Ear Disorders

Hearing has always been an essential part of communication – learning to talk is based on the ability to imitate sounds and mimic words used to speak. Without the ability to hear, communication can be difficult. The study of the ear, also known as otology, is the branch of medicine that examines the anatomy of the ear, its physiology, as well as diseases and disorders associated with it.

The ear is divided into 3 different sections, each playing an integral role in the hearing process: The external ear, middle ear, and inner ear.

Anatomy of the Ear

The external ear is the visible portion of the ear and consists of the pinna (or auricle) and the auditory canal. These parts of the ear are responsible for funnelling sound waves and secreting earwax. The tympanic membrane, also known as the eardrum, separates the external ear from the middle ear. A common disorder of the inner ear is impacted cerumen (earwax). This occurs when earwax has hardened and obstructs the auditory canal. Signs and symptoms of this condition include ear ache, blocked or muffled hearing, and a sensation of a plugged ear. Dr. Ali Ghahary, a Vancouver physician practicing at Brentwood Medical Clinic, treats this condition by flushing earwax with a syringe. If let untreated, it can lead to permanent hearing loss or tinnitus. 

The middle ear is a small cavity located in the temporal bone of your skull. It contains three bones that are commonly described by their shapes. These are the malleus, which is shaped like a hammer, the incus, which is shaped like an anvil, and the stirrup-shaped stapes. The middle ear is responsible for equalizing air pressure, sound vibration, and protection from damage (i.e. from loud noise.) Otitis media, inflammation of the ear, is a common disorder associated to the middle ear. It is caused by bacterial or viral infections. While it can affect individuals of all ages, it tends to occur in children more than adults. A child suffering from this condition may tug or pull on the affected ear, become unusually irritable, develop a fever and have difficulty sleeping. If infection is present, antibiotics will be prescribed. Decongestants may also be recommended to reduce swelling along with pain relievers. For more information on ear infections in children, click here.

The inner ear is responsible for converting sound pressure impulses to the brain via the auditory nerve. The most common disorder associated with the middle ear is tinnitus, which is characterized by ringing in one or both ears. There are various causes of tinnitus – from hearing loss, allergies, certain medications and even tumours. The ringing caused by tinnitus can be so severe that it can affect the ability to sleep and work. While there is no cure for this condition, many patients say they have found relief with hearing aids.

For persisting ear problems, Dr. Ali Ghahary will refer patients to an ENT (ear, nose, throat) specialist. There are also hearing clinics in and around Vancouver that are also well adept in conditions associated with the ear.

The Importance of Nutrients

Good nutrition has always been a key element in maintaining a healthy lifestyle, and is something Vancouver physician Dr. Ali Ghahary promotes. 


Nutrition is responsible the growth, repair and maintenance of the body. It is well known that the typical Canadian diet contains too much fat, too much cholesterol, too many calories, too much salt, not enough fibre, and insufficient complex carbohydrates (i.e. whole grains, beans and vegetables.) It is important to have a well-balanced diet with the proper proportion of nutrients; nutrients are the chemical substances found in foods that supply your body with the required elements for metabolism and energy. By doing so, you will greatly increase your quality of life.

The six main classifications of nutrients are as follows:

1. Carbohydrates
2. Proteins
3. Fats
4. Water
5. Vitamins
6. Minerals

Carbohydrates
Carbohydrates are the main source of energy from foods. These include the sugars (also known as simple carbohydrates), starches (the complex carbohydrates), and fibre (also known as cellulose.) Complex carbohydrates are beneficial to having a healthy diet as they are lower in fat, higher in fibre, and are a great source for other vitamins and minerals. Complex carbohydrates include vegetables such as yams, carrots and peas, citrus fruits such as oranges and grapefruits, as well as whole grains and pasta.


Proteins
Proteins are what from the base of each living cell within our body and are fundamental for growing and repairing tissue, giving our bodies energy, as well as contributing to the structure for our muscles, bones and blood.



Fats
Also known as lipids, fats are a dominant source of energy. They have two classifications: Saturated or unsaturated. In moderation, fats can benefit the body as they help to provide a source of energy, assistance in transportation of other vitamins such as A, D, E and K, and add taste to foods. However, many Canadians are consuming more fats than they should be.



Water
The body needs water in order to survive. Unlike food, which the body can survive without for several weeks, it cannot survive without water for more than a few days. Water has many health benefits and it is recommended that at least 6 to 8 glasses are consumed each day. However, the requirement for water intake is also based on an individual’s age, body size, metabolic rate and other factors.



Vitamins
Vitamins are organic substances that are essential for the body’s metabolism, growth and development. They are identified by an alphabetical letter and have two main classifications: Fat-soluble vitamins (such as A, D, E, and K) and water-soluble vitamins (such as B and C.) For more information on vitamins and their benefits, read Dr. Ali Ghahary’s articles titled ‘Vitamin D Important For Optimal Health’ and 'Vitamin D Deficiency'.



Minerals
These are inorganic elements that are found throughout the body and come from multiple sources. Fruits and vegetables, as well as milk, contain many different minerals such as calcium, phosphorus, iron and iodine. While minerals don’t provide the body with energy or calories, they do benefit hormones and heart contraction. To ensure you are getting your body the appropriate amount of minerals, try to buy organic fruits and vegetables 



Remember, the key to having a well-balanced diet is eating a variety of healthy foods. Make sure you are eating foods that are fresh as opposed to processed, as well as lean meat, poultry, and fish that is rich in omega-3 fatty acids. While sugary, sweet food can be pleasant to the taste buds, they are not nutritional and should be limited or cut from the diet all together.
