Feeling sleepy after eating a big meal or after an early morning is normal. While excessive sleepiness does raise alarm, the key to avoid it to understand what is triggering it.

Our bodies have an internal clock, called the circadian rhythm, that controls when we feel sleepy or awake. According to National Institute of General Medical Sciences (NIGMS), these rhythms include physical and mental changes an organism experiences over 24-hour cycle.

According to John Hopkins Medicine this clock makes us naturally feel a bit sleepy in the early afternoon, usually around 1:00 or 3:00 PM. It's like a built-in dip in our energy levels. Scientists have studied this, and they've found that we're usually most alert in the morning and early evening, with a little dip in between. In some countries, people used to take a short nap in the afternoon to deal with this. It's just a normal part of how our bodies work, but we can learn how to manage it.

Ways You Can Avoid The Afternoon Crash

Everyone gets sleepy in the afternoon sometimes. It's a normal part of life. But you don't have to let it ruin your day. Sometimes, feeling really sleepy during the day can be a sign of a medical problem. If you have a condition like sleep apnea or narcolepsy, or if you take medicine that makes you sleepy, you might feel extra tired in the afternoon. The natural dip in alertness makes it even worse for you. If you're feeling excessively sleepy during the day, it's important to talk to your doctor. They can help you figure out what's going on and find ways to feel more awake and alert. By taking care of your sleep habits, you can make it easier to get through the day without feeling tired all the time. Here are some ways you can avoid the afternoon crash.

Prioritize Sleep

Quality sleep is crucial. Aim for consistent bedtime routines and sufficient hours of rest. Sleep deprivation amplifies afternoon fatigue. A well-rested body manages energy dips more effectively, reducing the severity of the midday slump.

Increase Physical Activity

Even brief movement combats sleepiness. Stand up, stretch, or take a short walk. Physical activity boosts blood flow and oxygen to the brain, enhancing alertness. Regular, light activity throughout the day helps maintain energy levels.

Lighter Lunch Choices

Heavy, carb-loaded lunches divert energy to digestion, inducing sleepiness. Opt for balanced meals with lean protein and vegetables. Lighter meals prevent excessive energy shifts, helping you stay alert and focused in the afternoon.

Caffeine or Hydration

Moderate caffeine intake can temporarily increase alertness. However, avoid excessive amounts, especially later in the day. Hydration is vital; water improves circulation and cognitive function. Choose refreshing drinks to stay hydrated and energized.

Vitamin C Supplementation

Vitamin C's antioxidant properties may reduce fatigue. It combats oxidative stress, a contributor to tiredness. Consider a supplement or vitamin C-rich foods. Remember, individual responses vary, and it's best to consult a healthcare professional.

Shift Mental Focus

When feeling sleepy, change your mental environment. Focus on completed tasks or engage in enjoyable activities. Distraction can redirect your mind, temporarily alleviating the feeling of sleepiness. A brief mental break can provide a needed reset.

Power Naps

Short naps (20-30 minutes) can rejuvenate, but avoid longer naps. They can lead to grogginess. Napping too close to bedtime disrupts nighttime sleep. A brief nap during the early afternoon can restore alertness and improve productivity.

Irritable bowel syndrome (IBS) is often characterised by digestive symptoms like abdominal pain, bloating, constipation and diarrhoea. However, the condition involves more than the digestive system.

A new review published in The Lancet explains how interactions between the gut and brain, changes in the gut microbiome, immune activity and the body's response to pain can contribute to the development of symptoms.

The review, titled Irritable bowel syndrome and related disorders of gut-brain interaction, brings focuses on biological and psychological evidence behind IBS. Researchers describe it as a disorder of gut-brain interaction, in which signals between the digestive system and the central nervous system affect gut function.

The authors also discuss chronic constipation and functional diarrhoea, which belong to the bigger group of disorders related to gut-brain interaction. These conditions may affect an estimated 20% of the global population.

The gut and brain communicate continuously through a complex network that involves the central nervous system, autonomic nervous system, enteric nervous system and hypothalamic-pituitary-adrenal (HPA) axis.

The brain can influence intestinal movement, secretion and sensitivity, while signals from the gut can affect how the brain processes pain and other sensations.

In people with IBS, this communication may become disrupted. The result can be changes in bowel movements, more sensitivity to normal digestive processes and abdominal discomfort.

The authors said, “These central and peripheral mechanisms can act in an integrated way to cause IBS symptoms, via the gut-brain axis.”

For instance, a person with IBS may experience pain or bloating even when the amount of gas or intestinal movement would not cause discomfort in someone without the condition. This is due to a condition called visceral hypersensitivity, in which the nerves supplying the digestive organs become unusually sensitive to internal sensations.

The review explains that changes in both peripheral mechanisms within the gut and central mechanisms involving the brain can contribute to symptoms.

Gut Bacteria And Inflammation May Contribute To IBS

The gut microbiome, which consists of microorganisms living in the digestive tract, is another important part of the gut-brain connection.

Changes in the composition and activity of gut bacteria may impact intestinal function, immune responses and communication with the nervous system. The review identifies the following:

• Gut infections: Gastrointestinal infections can trigger IBS symptoms in some people, even after the initial infection has subsided.
• Altered gut microbiome: Changes in intestinal bacteria may affect digestion, immune activity and gut function.
• Increased intestinal permeability: Changes in the intestinal barrier may allow substances to pass through more easily, potentially contributing to immune activation.
• Low-grade inflammation: Mild inflammation in the intestinal lining and changes in immune function may contribute to symptoms.
• Abnormal gut movement: Changes in gastrointestinal motility can cause food and waste to move through the digestive tract too quickly or too slowly.
• Visceral hypersensitivity: Increased sensitivity in the gut can make normal digestive processes feel painful.

Mental Health And IBS

Psychological health is another component of the gut-brain axis. Stress, anxiety and other psychological difficulties can influence how the brain processes pain and communicates with the digestive system.

The HPA axis, which helps regulate the body's response to stress, plays a role in this process . Changes in stress levels can affect gut movement, secretion and sensitivity.

Currently, there is no single biomarker that can diagnose IBS. Doctors assess symptoms, medical history and clinical findings, while using tests to rule out other conditions.

The review highlights that some underlying mechanisms can already be measured through approved tests and questionnaires. These include abnormal bile acid metabolism, accelerated movement of contents through the colon and psychological conditions.

Does a patient’s chances of serious outcomes differ if they are treated by a female doctor? A recent study looks into this hypothesis to ascertain the difference between chances of a patient dying under a male and a female doctor.

According to the study, hospitalised patients treated by female doctors have a lower risk of dying within 30 days. They are also less likely to be re-hospitalised than those treated by male doctors. The study is published in JAMA Network Open.

"Past research has largely focused on surgical patients and the admitting physician only. Our findings add to the growing body of research examining the relationship between physician sex and patient outcomes, broadening the evidence beyond surgical care to a wider range of medical conditions and other physicians," says Dr. Angela Jerath, an ICES scientist, and Associate Professor, Department of Anesthesiology & Pain Medicine at the University of Toronto's Temerty Faculty of Medicine.

After analysing the health records of 958,150 adults admitted to hospitals in Ontario, Canada, between 2008 and 2022, researchers found that the 30-day mortality rate was 12.3% among patients treated by female physicians, compared to 13.7% among those treated by male physicians.

The findings also show a small difference in hospital readmissions. The 30-day readmission rate was 18.6% for patients treated by female doctors and 18.9% for those treated by male doctors.

The researchers examined outcomes across seven common medical conditions, including heart attacks, pneumonia and other acute illnesses.

They also considered the number of hospital days during which patients received care from female doctors, recognising that several doctors may be involved in a patient's treatment during an admission.

After accounting for patient, physician and hospital characteristics, treatment by a female physician was linked with 12% lower adjusted odds of death within 30 days compared to treatment by a male physician.

The researchers also found that for every 10% increase in the proportion of hospital days managed by female physicians, the adjusted odds of 30-day mortality decreased by 7%. This was observed for most medical conditions that were studied. Atrial fibrillation was the only exception.

The difference in mortality was also seen at longer follow-up periods. Patients treated by female physicians had lower mortality at 90 days and one year.

The findings were observed among both male and female patients. Female patients treated by female physicians had the lowest adjusted 30-day mortality rate in the analysis.

Why Patients May Have Better Outcomes With Female Doctors?

The study did not establish why patients treated by female physicians experienced better outcomes. However, the researchers discussed possible differences in clinical practice and communication.

Female physicians may be more likely to engage in patient-focused communication, spend more time with patients, follow clinical guidelines and involve colleagues in decision-making.

These practices could influence how symptoms are studied, treatment decisions are made and coordinated during hospitalisation.

"The goal is not to favour one group of physicians over another but to identify practices and behaviours that may help improve care across the health system," says Jerath.

"An important strength of this study is that, unlike surgical care, patients admitted to hospital for medical conditions are generally assigned physicians based on rotating schedules rather than patient or referring physician preferences, helping to minimize referral bias."

Eli Lilly's experimental weight-loss drug retatrutide, being referred to as ‘Godzilla’, continues to outperform its rivals like Ozempic.

According to a recent head-to-head Phase 3 clinical trial involving adults with type 2 diabetes, it delivered more than twice the average weight loss achieved with Ozempic.

Ozempic Vs Retatrutide

Participants who took the highest dose of retatrutide lost an average of 20.9% of their body weight over 80 weeks, compared to 9.4% among those receiving Ozempic's highest approved dose for type 2 diabetes.

The trial, called TRANSCEND-T2D-2, involved more than 1,000 adults with type 2 diabetes. It compared once-weekly injections of retatrutide at doses of 9 mg and 12 mg with semaglutide, the active ingredient in Ozempic, at 2 mg.

At the end of 80 weeks, participants taking retatrutide 9 mg lost an average of 44.3 pounds (20.1 kg), while those receiving the 12 mg dose lost 47.4 pounds (21.5 kg). The Ozempic group lost an average of 20.9 pounds (9.5 kg).

The findings mark the first Phase 3 head-to-head comparison of retatrutide with another medicine in this class.

Retatrutide Also Improved Blood Sugar

The trial found that retatrutide also resulted in produced greater reductions in HbA1c, a measure of average blood glucose over approximately three months.

At 80 weeks, participants taking either dose of retatrutide recorded an average HbA1c reduction of 2.2%, compared to 1.8 % among those receiving Ozempic.

The experimental drug also resulted in greater improvements in cardiovascular risk factors like non-HDL cholesterol, triglycerides and systolic blood pressure.

Side Effects Of Retatrutide

The most commonly reported side effects of retatrutide were gastrointestinal symptoms like diarrhoea, nausea, constipation, vomiting and indigestion.

Diarrhoea was reported in 28.3% of participants receiving the 9 mg dose and 32.7% receiving 12 mg, compared to 26.4% in the Ozempic group. Nausea occurred in 21.2%, 23.8% and 21.3% of participants, respectively.

Researchers also reported a higher incidence of dysesthesia, an abnormal sensation that can include tingling, burning or skin sensitivity, among participants taking retatrutide.

Treatment discontinuation because of side effects occurred in 4.8% of the 9 mg group and 7.9% of the 12 mg group, compared to 2.7% of the Ozempic group.

More About Retatrutide

Retatrutide is a once-weekly injectable drug that targets three hormone receptors involved in regulating appetite, blood sugar and metabolism. They are GLP-1, GIP and glucagon.

GLP-1 helps regulate appetite and blood sugar while slowing the process of stomach emptying. GIP also plays a role in glucose regulation and insulin release. Glucagon is involved in controlling blood glucose and energy metabolism.

Ozempic, manufactured by Novo Nordisk, acts on the GLP-1 receptor. Eli Lilly's Mounjaro and Zepbound, which contain tirzepatide, target both GLP-1 and GIP receptors.

Retatrutide remains an investigational drug and has not been approved by the US Food and Drug Administration (FDA) or other regulatory authorities.

Eli Lilly plans to submit the drug for FDA approval in early 2027. The company said detailed results from the trial would be presented at a future medical meeting and published in a peer-reviewed journal.
