Diabetes - Symptoms, Causes, Precaution, Methods and more

Image
  DIABETIES :- Diabetes Mellitus is a chronic metabolic disease. which is characterised by hyperglycemia resulting from insulin deficiency or insulin resistance. Diabetic Mellitus SYMPTOMS :- 3P :-  Polyuria (frequent urine)   Polyphagia ( very hungry)  polydipsia ( very thirsty) feeling tired blurry vision weight loss  delay wound healing HYPERGLYCEMIA High blood sugar/ high sugar level in blood. HYPOGLYCEMIA   Low blood sugar with a glucose value of usually less than 70mg/dl CAUSES To high dose of medication ( Insulin/ antidiabetic medication ) Delayed Meals Exercise Alcohol SYMPTOMS Shakiness Anxiety Sweating Irritability or Confusion Fast heart beat Dizziness Hunger and nausea Headaches Weakness Seizure/Unconsciousness TREATMENT Consume simple carbohydrates like half cup sweetened juice, 3 tablespoons of sugar, honey, chocolates or hard candy. Recheck your blood glucose after 15 minutes. If hyperglycemia continues, repeat the glucose supplements. Once blood glucose returns to nor

Anatomy Of Human Brain, Parts, functions, Lobes, Cranial Nerves, Neuron & Diagram

Image
  HUMAN BRAIN   Brain is a organ of soft nervous tissue contained in the skull of vertebrates, functioning as the coordinating centre of the body. PARTS OF BRAIN Human brain is divided into three major parts on the basis of their functions and placement :-  1. Fore Brain  2. Mid Brain  3. Hind Brain  DIAGRAM OF HUMAN BRAIN 1. FORE BRAIN :-    It is the anterior part of the brain  It has three parts :-  Thalamus Limbic System Cerebrum THALAMUS :- it is located above the brain stem and between the cerebral and Mid-Brain. FUNCTION :- It carries sensory information from the body to cerebrum and the limbic system. HYPOTHALAMUS :- It lies under the thalamus. FUNCTION :- It connects the nervous system with the endocrine system via pituitary gland. LIMBIC SYSTEM :- It is arc shaped structure between thalamus and cerebrum. FUNCTION :- It controls responses like :- Hunger Fear Thirst Anger   Sexual responses etc. CEREBRUM :- It is divided into two halves called cerebral hemisphere. They communi

Atrial Fibrillation/Atrial Flutter

Image
  Atrial Fibrillation  Atrial Flutter Atrial Fibrillation   (Afib) Afib stands for atrial Fibrillation (AF) Atrial Fibrillation is a type of arrhythmia or abnormal heart beat and is a major cause of stroke.  Atrial Fibrillation is an irregularly irregular and often very rapid heart rhythm that begins in heart upper chambers (Atria). in which the upper chambers of the heart (atria) beat out of coordination with the lower chambers of the heart (ventricle). ATRIAL FIBRILLATION FINDINGS ON ECG Findings Irregularly irregular QRS Complex P wave absent / no visible P wave present Heart beat range (100bpm - 160bpm) Types of Atrial Fibrillation There are three main types of atrial fibrillation.... Paroxysmal atrial Fibrillation Persistent atrial fibrillation Long standing persistent atrial fibrillation Paroxysmal Atrial Fibrillation It's episodes occurs less than one week and usually stops on its own without treatment. Persistent Atrial Fibrillation It's episodes occurs more than one we

What is coronavirus/ COVID-19 ? Symptoms & Complications

Image
What is coronavirus ? Coronavirus is a type of virus. it is a largest category for an RNA virus. there are many different kinds, and some cause disease. a coronavirus disease COVID-19 as an infection disease identified in December 2019, caused by SARS-CoV-2 virus, a pandemic of respiratory illness, called COVID-19. SARS-CoV-2 stands for Severe Acute Respiratory Syndrome.   COVID-19 stands for :-  'CO' stands for corona,  ' VI' stands for virus ' D' stands for disease. This disease was referred to as '2019' novel 'coronavirus' or '2019-nCoV'. The coronavirus is a new virus linked to the same family of viruses as SARS and some types of common cold.  Where was COVID-19 first discovered ? The first known infection from SARS-CoV-2 were discovered in Wuhan, China. Who issued the official name of COVID-19 ? The official names of COVID-19 and SARS-CoV-2 were issued by the WHO on 11 February 2020. How does COVID-19 spread between people ? We known

What is Cardiac Axis ? How to determine cardiac axis in ECG/EKG by thumb rule ?

Image
 Cardiac Axis  The average direction of spread of the Depolarization wave through the Ventricles as seen from the front is called "cardiac Axis".                                    Or  Cardiac axis describe the overall direction of electrical spread within the heart. NOTE -   It is usual to decide whether this axis is in a normal direction or not. Lead aVR and lead II look at the heart from opposite directions. when seen from the front, The depolarization wave normally spreads through the ventricles from 11 O 'clock' to 5 O 'clock', so the deflection in lead aVR are normally mainly downward -ve and in lead II mainly upward +ve.  Normal Axis A normal 11 O 'clock - 5 O' clock axis means that the Depolarizing wave is spreading towards lead I, II and III,                  and is therefore associated with a predominantly upward deflection in all these leads. NOTE -   The deflection will be greater in lead II than in lead I and than in lead III.  Right Axis
