Hypertension

Hypertension is defined as a persistent high blood pressure against the walls of a patient’s arteries. A high blood pressure is defined as a numerical value exceeding 140/90 mmHg, the numerator and denominator represents systolic and diastolic pressure respectively. 

Hypertension damages blood vessels over a prolonged period of time, which leads to a range of cardiovascular diseases such as stroke, aneurysm and heart attack. 


Some symptoms include headache, high blood pressure and dyspnea (difficult or laboured breathing) possible retinopathy, chest pain and sensory or motor problems.


If hypertension persists, it can induce end organ damage, which is the damage of major organs fed by the circulatory system. Renal failure and a loss of vision are some examples of end organ failure.

Kidney Stones

Renal calculi, or kidney stones is the formation of crystals in the kidneys causing excretory issues. These stones mainly form in the renal pelvis or the ureter in the kidney. It is accompanied by symptoms such as nausea, vomiting and a burning sensation when urinating  Urine consists of salts and various compounds such as Calcium, Potassium, Sodium, Oxalate, Phosphate and Uric acid. Calcium oxalate is the most common stone formed in the kidneys, it accounts for 80% of kidney stones The crystals can scratch the walls of the urinary tract, sending nerve impulses to the brain causing excruciating abdominal pain. The scratches also cause blood vessels embedded behind the walls to burst, causing blood to enter the urinary system. This causes the patient to urinate blood. IF the stone is big enough to cause a blockage in the urinary tract, this can create a backflow of urine and infect the kidneys itselves. However, most kidney stones do not grow large enough to cause a blockage. This w...

Parkinson's Disease

Parkinson’s disease is a progressive nervous system disorder that affects one’s movements. Parkinson’s disease signs and symptoms are different for every individual and may go unnoticed in the early stage. Symptoms typically start on one side of the body and remain worse on that side even after the symptoms begin appearing in both sides of the body.  Generally, the symptoms of Parkinson’s disease include tremors, slowed movement, rigid muscles, impaired posture and balance, loss of automatic movements such as blinking or swinging of arms when walking, and speech and writing changes.  Parkinson’s disease occurs when neurons in an area of the brain that controls movement becomes impaired or dies. These neurons normally produce dopamine. As more neurons become impaired or die, the amount of dopamine produced in the body is reduced significantly, causing the movement problems associated with Parkinson’s disease.  People with Parkinson’s also lose the nerve endings that produc...

Horner’s Syndrome

Horner’s syndrome is a condition where the sympathetic nerves on the face are damaged. 3 classic signs of Horner’s syndrome include miosis (constriction of the pupil), ptosis (drooping of the upper eyelid) and anhidrosis (absence of sweating of the face). It is a result of other medical problems such as stroke, tumor or spinal cord injury. Hence, treatment for the underlying issue may restore nerve function. The nerve pathway affected in Horner’s syndrome is divided into three groups of neurons called the first, second and third order neurons. These neurons lead from the hypothalamus of the brain through the spinal cord and finally along the facial skin and muscles of the iris and eyelids  Sources: https://rarediseases.info.nih.gov/diseases/6670/ horners-syndrome
