Autophagy, derived from a Greek word, the "self-eating" nature refers to an interesting cellular process as part of the body's own recycling mechanism for cellular damage or components that have no purpose. This natural cleansing biological mechanism assists in maintaining health and restoring cellular structures through break-down and repurposing the dysfunctional components, generating energy, and rebuilding new structures for cells.
In the recent past, autophagy has been in the headlines as a potential factor toward achieving health benefits that run from anti-aging features to preventing chronic diseases.
Learn how autophagy works, its potential health impacts, and how individuals might harness this natural process for better health and longevity.
Autophagy is an essential process in which cells remove their "junk" components - such as damaged proteins, malfunctioning organelles, or harmful pathogens, such as bacteria and viruses, which would otherwise interfere with proper cellular functioning. This autophagic housekeeping maintains cell functionality and allows them to recover from stress or nutrient depletion.
The breakdown products of these cellular wastes are amino acids during autophagy, which the cell reuses to build new proteins for energy creation or to restore and replace damaged cells. In effect, the body is recycling itself on the microscopic level, boosting survival and efficiency of its cells.
Autophagy occurs in the cytoplasm, which is the jelly-like fluid inside cells. The whole process occurs in the following steps:
The dysfunctional parts of the cell are engulfed by a double-membraned structure known as a phagophore, which gives rise to an autophagosome.
The autophagosome fuses with lysosomes, which are special structures containing enzymes that degrade waste materials.
Lysosomal enzymes degrade the trapped cellular components into their building blocks, such as amino acids.
The produced amino acids are then reutilized for energy or protein synthesis to build new proteins and cellular structures.
In this way, cells manage to remain viable in situations of nutrient starvation or stress, increasing their efficiency and resilience.
The researchers have linked autophagy to numerous health benefits although much of the current knowledge is based on animal studies. Some of the significant ways autophagy can promote health include the following.
Autophagy is often described to be an anti-aging process. It helps remove the damaged or dysfunctional cellular components so that the process can slow the rate of cellular aging, reduce inflammation, and even enhance tissue regeneration.
Autophagy is very crucial in preventing chronic diseases. For example:
Neurodegenerative Diseases: It could help in clearing abnormal protein buildup, for instance, those found in Alzheimer's and Parkinson's diseases.
Liver Health: Autophagy may prevent damage caused to the liver by alcohol, drugs, or conditions known as fatty liver.
Cancer: While autophagy may inhibit early tumor growth by removing damaged cells, it can also aid cancer cells’ survival under certain conditions, underscoring the complexity of its role.
By recycling damaged components, autophagy supports metabolic efficiency, potentially reducing the risk of obesity, type 2 diabetes, and other metabolic disorders.
Autophagy helps eradicate harmful pathogens and contributes to a more robust immune response, allowing the body to fight infection better.
Although autophagy is a physiological process, there are a few lifestyle modifications that have been known to enhance or trigger it. Here are several potential triggers:
Probably, one of the most studied autophagy triggers is fasting. Fasting cells switch to survival mode and start breaking their components down for energy production. It has been observed that fasting periods of 24 to 48 hours trigger autophagy.
Even partial fasting has been proven to stimulate autophagy. Nutrient deficiency forces cells to recycle components for energy.
Physical activity stresses cells and causes damage, which autophagy can repair. Regular exercise does not only induce autophagy but also promotes the overall cellular and metabolic well-being of an individual.
A high-fat, low-carbohydrate diet may push the body into autophagy by forcing it to obtain energy from fat rather than glucose. Such a change in metabolism will enhance cellular cleaning abilities.
Curcumin, the active ingredient in turmeric, has been reported in animal studies as an autophagy inducer. Yet, more human studies will be required; however, curcumin's properties as an anti-inflammatory agent and antioxidant make it worthwhile for further investigation.
Fasting perhaps represents the most well known form of autophagy induction. When the organism lacks food, it enters the catabolic state and has to recycle internal elements for survival.
Research has indicated that short-term fasting may actually induce autophagy in the brain, although it is still an area of active research. However, fasting should be done with extreme care because long-term deprivation can cause nutrient deficiencies and other health risks.
Although the benefits of autophagy are promising, there are limitations and risks associated with trying to induce it artificially:
For these reasons, consultation with a healthcare provider before such significant lifestyle modifications would stimulate autophagy. Autophagy is that beautiful cellular mechanism that underscores the ability of the body to heal and regenerate and to respond to stress. Although it will require more research for further details on its implications, health benefits are numerous; anti-aging effects as well as prevention of chronic diseases fall under this wide-ranging aspect.
If you’re interested in exploring ways to promote autophagy, consider integrating fasting, regular exercise, or a balanced diet into your routine. However, as with any health intervention, it’s crucial to approach these strategies with caution and under the guidance of a healthcare provider.

Ten-year-old Myla from the UK's North Yorkshire, with severe eye strain, was diagnosed with a severe brain tumor that led to her death.
The young girl had been suffering from headaches and dizziness, which were dismissed as mere eye strain due to playing on her iPad too much.
Thinking that she needed eyeglasses, her parents took her for an eye appointment, where she was diagnosed with an aggressive diffuse midline glioma — a type of brain tumor.
Myla was diagnosed with a 7-10cm tumor and was rushed to Sheffield Children's Hospital for an operation to remove 60 per cent of the mass. The youngster underwent a grueling 30 rounds of radiotherapy but tragically passed away on January 15, The Mirror.co.uk reported.
Healthandme spoke to health experts to understand the role of eye strain and brain tumors.
The health experts noted that although prolonged exposure to digital screens can raise the risk of vision problems, they cannot cause brain tumors.
"Eye strain is most commonly linked to prolonged screen use, poor ergonomics, or uncorrected vision, and in the vast majority of cases, it is not a sign of brain cancer," Dr. Parul Maheshwari Sharma, Ophthalmologist and Principal Director & HOD - at Fortis Gurugram, told HealthandMe.
"The likelihood of experiencing eye strain being an indication of brain cancer is minimal," added Dr. Mahipal Singh Sachdev, Chairman & Medical Director, Centre For Sight Group of Eye Hospitals.
The doctors explained that brain tumors are rarely present as simple eye strain; they are usually associated with additional symptoms such as:
Eye strain, also referred to as digital eye strain or computer vision syndrome, is caused by staring at screens for extended periods of time and decreased blinking.
It generally occurs due to benign factors such as excessive screen time, dry eye, or uncorrected vision.
While prolonged screen use can cause discomfort, dry eyes, and temporary blurred vision, it does not lead to the development of cancer.
"There is no evidence to suggest that screen-induced eye strain can cause brain tumors," Dr Sharma said.
"Although there may be visual changes due to a tumor that involves the optic nerve or hypothalamus, simple eye strain is not indicative of brain tumors and would not be considered an early warning of a brain tumor. There is an extremely low probability that eye strain will be due to a brain tumor," Dr. Sachdev told HealthandMe.
However, the experts agreed that long screen time can lead to severe eye strain.
Brain tumors are generally attributed to genetics, exposure to radiation, or other unknown factors.
Numerous types of red flags could indicate the presence of a serious neurological disorder. Some examples include

Ladies, does it ever happen to you that you are not on your period, not PMSing, and still feel moody and upset? Well, as it turns out, experts say that there could be a very simple reason for this. According to researchers at the University of Connecticut, even mild dehydration could be responsible for mood changes in women. Not only this, even 1.36 per cent dehydration can affect your mood, ability to think and energy levels. The Daily Mail notes that a loss of 1.5 per cent of normal water volume levels in the body can be classified as mild dehydration, and its adverse effects can linger for some time.

In women, the adverse effects of dehydration can be serious. Experts say that the effects are more intense in women, and they came to this conclusion after analysing the results of tests, which revealed that it does not matter if a person walks for 40 minutes on a treadmill or is in a state of rest — if an individual is even slightly thirsty, the adverse effects will be the same.
Research shows that even 1.36 per cent dehydration is enough to cause the following problems:
Is thirst the same as dehydration?
Lead researcher of the study, Lawrence Armstrong, noted that a sensation of thirst does not appear until a person is one or two per cent dehydrated. By then, it starts to set in and act up, adversely impacting how the mind and body perform. Dehydration can affect everyone, which is why it is just as important for people in desk jobs to stay hydrated as it is for marathon runners.

In this research, experts put participants through a series of tests evaluating their concentration, vigilance, reaction time, reasoning, memory and learning. The results were then compared with those of people who were not dehydrated. In younger women, mild dehydration resulted in fatigue, headaches and concentration difficulties. Women also found basic tasks more difficult to execute than usual. On the other hand, young men noted some difficulty in performing mental tasks — they experienced anxiety, fatigue and tension in the process. Mood changes were more prominent in women than in men.
The oral microbiome is the community of bacteria, fungi, and other microorganisms that naturally live in the mouth — on the teeth, gums, tongue, and cheeks. More than
700 species are known to exist, most of which are harmless and many beneficial.
However, problems arise when harmful bacteria outnumber protective ones, leading to gum inflammation or periodontal disease. During pregnancy, hormonal changes increase blood flow to the gums and alter immune responses. As a result, many women notice bleeding, swelling, or sensitivity in the gums — a condition known as pregnancy gingivitis.
This is common and reflects physiological changes rather than poor hygiene.
Pregnancy is a systemic state in which the immune system, circulation, and inflammation are closely interconnected. Chronic gum inflammation can release inflammatory mediators into the bloodstream.
In research settings, certain oral bacteria have also been detected in placental tissues from complicated pregnancies. This suggests a biological link between oral health and
placental function, although the exact pathways are still being studied.
Importantly, this relationship reflects association rather than direct causation.
The placenta is an active organ that regulates oxygen and nutrient transfer, hormone production, and immune protection for the developing baby.
Healthy placental development supports:
Up to 60–75 percent of pregnant women experience some degree of gum inflammation. Common changes include:
Research from India and globally shows associations between periodontal disease and higher risks of preterm birth, low birth weight, and preeclampsia. Meta-analyses
suggest a modest increase in risk (around 1.5–2 times).
However, pregnancy complications are multifactorial. Oral disease alone does not directly cause these outcomes. Genetics, nutrition, metabolic health, and placental
biology all play important roles.
Treating gum disease improves oral health and reduces inflammation, though studies show mixed evidence on whether it directly lowers preterm birth risk. The goal is
prevention, awareness, and overall maternal health.
Daily oral care:
Pregnancy already carries emotional and physical changes, and dental symptoms can add anxiety. Support from partners and family members helps reduce mental load.
Stress can influence immunity and inflammation. Adequate rest, gentle activity such as walking or prenatal yoga, and open communication with healthcare providers
support both oral and overall health.
Seek professional advice if you notice:
Pregnancy is a time when different systems of the body work in close coordination. Oral health, immune balance, and placental function are part of the same continuum.
Gentle attention to gum health is not about perfection. It is about creating supportive conditions for a healthy pregnancy and a healthy baby.
