Patient concerns

Main problem : I keep feeling too sleepy throughout the day. I have so many things to do related to my career, family and social life but this problem has been consuming most of my quality time, brings down my energy making me too less productive. I have been reading about this thing over Internet and what I can figure out myself is that my problem seems to be too close to Narcolepsy.
Dr. Jyoti Kapoor Madan
Psychiatry
Narcolepsy is sudden uncontrollable bout of sleepiness. Often sleep problems are due to poor quality of night time sleep. You may go for a sleep study or polysomnography to identify sleep related issues and tackle the problem easily.
palpitation tachycardia hypertension loud snoring daytime sleepiness
Dr. Jyoti Kapoor Madan
Psychiatry
Anxiety is the result of a hyperarousal state of nervous system due to a low threshold for threat perception. In simpler words, it's an ongoing flight or fight response. It can elicit a neuro-hormonal response understood as Flight or Fright reaction kicking in physiological cascade of symptoms ranging from palpitations, tachycardia, breathlessness, increased bowel movement, increase frequency of urination, dizziness, muscle tension or pain, trembling, dizziness, blurring of vision to restlessness, confusion and fainting spells. Chronic stress causes prolonged anxiety response with the consequences of slowed cognition , lack of concentration, headaches, fluctuations in blood pressure, irritable bowel syndrome with persistent Bowel movement issues and increased wear and tear of body tissues. Identifying your stressors, learning to deal with them, de stressing regularly by doing something that makes one feel good, yoga and meditation are some non pharmacological strategies to deal with it. If the condition is persisting for a long time, it's better to see a psychiatrist.
