Running as a form of aerobic exercise increases longevity, but there are other factors to consider too.

The news of Jogi ji's passing away due to cardiac arrest during sleep is shocking. Our heartfelt condolences🙏

1. Joginder Chandna ji was extremely fit and had amazing statistics for a long-distance runner. His PB for 5k, 10k, HM and FM were 23 min, 46 min, 1:39 hours and 3:40 hours.
2. He had an amazing control over heart rate while running long distances. His latest long run (23 Km) was on Sunday, 28th July (2 days before we lost him). An AHR of 127 bpm (and a max HR of 139 bpm) for a pace of 6:50 min/Km is amazing.

By the time diabetes mellitus is diagnosed, it is already too late.

Take control when insulin resistance sets in. Or may be even before that.

Low carbohydrate diet and regular exercise are the keys to prevent insulin resistance, prediabetes and type 2 diabetes.

Ref: (1/n)doi.org/10.3390/antiox… Lifestyle tips to manage insulin resistance

1. Lose excess weight (especially abdominal and visceral fat),
2. Engage in regular physical activity,
3. Sleep well,
4. Minimize stress,
5. Reduce carbohydrate intake,
6. Quit smoking.

Running and heart diseases
Learning points from the past 30 years of published research

1. Runners have a lower risk of heart attack, as compared to people leading sedentary lifestyles,

2. Runners are 45% less likely to die from heart disease than non-runners,

3. The benefit starts with as little as 10 minutes of running per day, and increases with increasing running duration up to 60 minutes. There is no additional mortality benefit from running beyond 60 minutes per day (or beyond 7 hours per week),

4. In terms of distance, the benefit starts with 1 mile (1.6 km) of running and increases with greater running mileage. There is no established upper limit beyond which running is detrimental to heart health, however, benefits may plateau beyond 80 km of running per week,

5. Runners have a lower resting heart rate. Lower resting HR is associated with greater longevity,

6. Running has a favourable effect on risk factors for heart attack. Running is associated with higher HDL-cholesterol, lower LDL-cholesterol, lower triglyceride, lowering of BP, improved insulin sensitivity, lower HbA1C level and lower body mass index,

7. Sudden cardiac arrest during long distance running is rare. The incidence is 0.8 per 100,000. The fatality due to sudden cardiac arrest during running is 0.4 per 100,000,

8. Majority of cardiac arrests occur while a person is sleeping, sitting or standing; only a miniscule of them occur while a person is running or doing some form of exercise,
9. Sudden cardiac arrests that occur during marathons make it to the headlines, as they are dramatic, unexpected and those affected are younger and fitter,

10. Marathoners have a greater chance of surviving a cardiac arrest, as compared to non-runners,

11. Sudden cardiac arrest during running is more common among men as compared to women,

12. Sudden cardiac arrest during running is most often NOT caused by running. However, running may precipitate sudden cardiac arrest among people with pre-existing cardiac diseases,

13. The commonest cause of sudden cardiac arrest in people aged 35 or less is hypertrophic obstructive cardiomyopathy,

14. The commonest cause of sudden cardiac arrest among people above 35 is coronary artery disease (due to blockage of artery supplying blood to the heart muscles),

15. The ideal average heart rate while running is 180 minus age (ref: MAF method). This ensures better recovery between runs, reduces the risk of injuries, and allows adaptation of the heart for better pace during races,

16. A good night sleep (7-8 hours) before a long run is of paramount importance,

17. Periodic hydration/nutrition breaks during a long run is also important. Dehydration, exhaustion, fatigue, and heat stroke can lead to a runner collapsing during a marathon,

18. If the body gives signals, such as dizziness, breathing difficulty, chest pain, tightness in chest, severe fatigue, or light-headedness, during a run; withdraw from the run and seek immediate medical help,

19. Do not start a run with a pre-meditated pace or finishing time. Alter thepace (increase or decrease) based on the route, elevation, temperature, how you feel and other race-day factors,

20. Long distance running is not a competition to be ahead of others. It is a passion to be enjoyed and cherished. Enjoy the entire run and not just the chip time.

Dr Sudhir Kumar MD DM 26-01-2024 There are various causes for cardiac arrest among runners and they differ based on the runner's age. Survival depends on the underlying cause of cardiac arrest; prompt performance of CPR (by the bystander) and use of defibrillator (on site).

Why are teenagers (adolescents) getting affected by heart attacks?

1. Heart attacks commonly affect older people. However, we have seen a recent increase in number of young people and even teenagers getting affected. What are the underlying reasons? 2. It is easy to put the entire blame on Covid 19 illness & covid vaccines, but that won't do proper justice (to our youth). There are several other possible reasons that have increased the risk of heart attacks in younger population, including adolescents. Let us look at them:

Tips for NMDC Hyderabad Half Marathon

Hyderabad marathon is scheduled on August 27th (3 weeks from now). It is one of the most popular marathons in the country and many of you may be planning to run here. I have done two half marathons on this route.
Sharing my experience
1/n https://t.co/0XGzatZkIatwitter.com/i/web/status/1…
The HM flag off time is 6 AM. Location is near Necklace road (Hussain Sagar lake, Secunderabad). Since one needs to assemble by 5 AM, it would be wiser to stay closer to this location, or make advance transport arrangements accordingly. Ample parking space is available.

A woman whose head dropped and eyes closed after talking to someone for 30 minutes or more

1. 49-year old Mrs Jhuma consulted me with a strange problem for one month. Whenever she talked with a friend or family member for 30 min or more, her head dropped forwards.
#MedTwitter twitter.com/i/web/status/1… 2. In addition, her eyes closed. She could not voluntarily raise her head or open her eyes. However, after taking rest for a few minutes, she was able to raise her head & open eyes.
She had no other problems.
She consulted local doctors without any success.

Neurological problems that occur or get worse with sleep
1. In addition to providing relaxation and rest, sleep has many health-related benefits. However, there are some problems that occur only during sleep (or they get aggravated in relation to sleep). Here are some of them: twitter.com/i/web/status/1… 2. Hypnic jerks
As one is falling asleep (period of transition from wakeful to sleepy state), about 70% people experience brief jerky movements of arm or leg (like a twitch). It is usually mild, however in some, it can be so severe as to disrupt the sleep of person or partner.

Long siesta (napping) is associated with obesity & metabolic syndrome

1. In a recent cross sectional study, the association between siesta- no siesta, short siesta (<30 min) and long siesta (>30 min)- and diabetes, obesity, hypertension and metabolic syndrome (MetS) was studied. twitter.com/i/web/status/1… 2. Compared with the no-siesta group, long siestas were associated with higher values of Body mass index (BMI), waist circumference (WC), fasting glucose, systolic blood pressure (SBP), and diastolic blood pressure, as well as with a higher prevalence of MetS.

An accidental doctor

1. I remember my first day in college-eight of us seated around a table, with a cadaver (with strong smell of chemicals used to preserve dead body) placed on it, ready to learn anatomy (of human body) by dissecting various parts, under guidance of a tutor. 2. This is not the kind of “welcome” that I had imagined (on day 1 in MBBS). I had no clue what to expect, as no one in my family was a doctor. I had taken the long journey (from Bihar to CMC Vellore) to become the first doctor among our extended family.

Nagging pain in the neck could be a symptom of migraine

1. Headache is the commonest symptom of #migraine. Other recognized symptoms are nausea, vomiting, hypersensitivity to bright lights and noise.
Neck pain is often attributed to slipped disc in neck region or muscle spasm. 2. I routinely see patients, in whom, the main problem is neck pain, or their pain starts in the neck, which radiates to head (usually frontal region and around eyes).
Both these situations can commonly occur with migraine.

When Manya paused after taking only five phere with her husband-to-be…
1. Manya was excited as she was getting married to Sanju, her childhood crush.
Wedding preparations, including shopping had gone on for 6 months. The week preceding the wedding day had been hectic for Manya. twitter.com/i/web/status/1… 2. The wedding ceremony was going well with friends & family from both sides meeting each other after long (due to intervening Covid). There was happiness & smiles all around.
Manya & Sanju were tired after night-long rituals, however, it was nearing the end with saat phere.

2023: Age 52; Wt 70 Kg, finished 10 Km run in 49 min 16 sec

Here I briefly outline how I made it possible:
#runningmotivation #running #weightloss #fitness #fitnessjourney https://t.co/NPF1xtOKUUtwitter.com/i/web/status/1…
1. Work life balance
*Reduced working hours to 8-9 hours (from 12-13 hours)
*Increased sleeping time to 7-8 hours (from 5-6 hours)
*Preponed dinner time to 7 PM instead of 10 PM
*Started sleeping at 10 PM instead of 1 AM, and getting up at 5 AM instead of 7 AM

1. Ms Shivi to me: “Dr. I am a burden on my parents. I am good for nothing. I have wasted my parents’ hard-earned money. All my friends are better than me. I wish I could just die so that my parents would be relieved.”
#MedTwitter #NeuroTwitter #psychtwitter twitter.com/i/web/status/1… 2. 18-year old Shivi was brought to OPD with repeated convulsions for 3 days. She was taken to physician in her village, who started her on anti-epileptic drugs (AEDs). Despite being on two AEDs at maximum doses, her convulsions continued. Physician referred her to a neurologist.

Exercise may erase the genetic risk of type 2 diabetes (T2D)
1. Exercise reduces the risk of developing T2D.
A recent research looked at the association between types (moderate-vigorous versus light) & duration of physical activity on risk of developing T2D.
#diabetes #exercise twitter.com/i/web/status/1… 2. 68.4 min/day of moderate-vigorous physical activity (MVPA) was associated with a 74% lower risk of developing T2D when compared with participants who spent less than 5.2 min in MVPA.

Less common symptoms of stroke

1. Weakness of one side of face, arm or leg; and speech impairment are the commonest symptoms of stroke.
However, it is important to be aware of lesser known symptoms of stroke, so that an early diagnosis can be made.
#MedTwitter #stroke twitter.com/i/web/status/1… 2. Sudden onset Confusion- due to involvement of speech area (located in left side of brain) concerned with comprehension of spoken words. Patients are unable to appropriately respond to queries and keep talking something that doesn't make sense. (Sensory or Wernicke's aphasia).

10 commonly asked questions about stroke answered

1. Stroke affects heart

#stroke affects brain and causes paralysis.
#heart attack is known by the term myocardial infarction.
#MedTwitter #NeuroTwitter twitter.com/i/web/status/1… 2. Common symptoms of stroke:
SUDDEN ONSET
*Weakness of arm, leg or face, usually on one side

Patients with Inflammatory bowel diseases (IBD) have a higher risk of suffering a stroke

1. Persons with Crohn's disease or ulcerative colitis have an increased risk of developing thrombo-embolic events. A recently published study looked at the association between IBD & stroke. twitter.com/i/web/status/1… 2. >85,000 patients with IBD were followed up long-term (1969-2019), and the risk of stroke in them was compared to those without IBD.
Patients with IBD had 14% higher risk of suffering from ischemic stroke during follow up.

Investment tips for doctors

It is a fact that most of us lack the basics of managing our finances. It is not unusual to come across doctors who have little awareness about their income, expenses & future goals (for which money is needed). Here are some tips that could help. twitter.com/i/web/status/1… 1. Life insurance: If you have dependents (children, spouse), life insurance is a must to safeguard their future in case of any unexpected incidents. Life #insurance is to protect the risk, and not an investment to get returns. Term plans are good.

1. Mr Hari to his wife Mrs. Rani: "Have you lost all shame? Why are you changing dress in the living room, where our driver is waiting?"

Mr Hari had noted instances of mood swings in his 55-year old wife for the past six months but today's incident was shocking.
#MedTwitter twitter.com/i/web/status/1… 2. Mrs Rani was otherwise a pleasant woman, however, she had become irritable for the past few months. She would get agitated over small issues and go into a shell (for several hours) on many occasions. She would refuse to talk to her husband and even refuse food.

Lower resting HR and its benefits

1. Today's resting HR was in 30s (39 bpm) again (usually it is 40-42 bpm). My original resting HR (in Nov 2020) was 72 bpm (prior to taking up running). With consistent running, resting HR dropped by about 30 bpm in about two years.
#Heartbeat twitter.com/i/web/status/1… 2. In the general population without known coronary artery disease and heart rate lowering medication, elevated resting HR (RHR) is an independent risk marker for all-cause mortality (death).

Ten lesser-known symptoms that could point towards a diagnosis of brain tumor

June 8th is celebrated as “World brain tumor day” to raise awareness about brain tumors. I would like to focus on the symptoms, presence of which, can make one suspect the presence of brain tumor. twitter.com/i/web/status/1… Common symptoms of brain tumor include headache, vomiting, reduced alertness, fits & paralysis. However, in several cases, these classical symptoms may be missing. It is important to know the lesser-known symptoms of brain tumors so that they can be diagnosed & treated early.
