Fasting may reset your body, but can it reset your mind? The new trend of dopamine fasting claims it can. And wait, there's more. This trend also works against dopamine resistance, implying that things that did not make you happier before will now do. You see, dopamine is a part of the brain's reward system and plays an important role in your pleasure reception. While this neurotransmitter is not directly linked to an individual's happiness, it triggers feelings of satisfaction, motivation and pleasure.

However, a person can also reach a stage of dopamine resistance if they continue to indulge in activities that trigger its frequent or constant release. In this case, the individual stops feeling the impact of this neurotransmitter and thus, does feel good or happy.

So does dopamine fasting work?

Dopamine fasting is a practice where individuals limit their exposure to activities or stimuli that typically provide a surge of dopamine. The idea behind dopamine fasting is to reset or recalibrate the brain's reward system. This is usually done by abstaining from gratifying things or experiences like social media, junk food, and even sex. Proponents of dopamine fasting argue that continual overstimulation from digital devices, social media, and easily accessible indulgences has numbed our brain's reward pathways. By regularly denying ourselves these dopamine triggers, the idea claims, we might restore our ability to acquire fulfilment from life's basic pleasures.

How Does Dopamine Imbalance Affect Your Mental Health?

Having low levels of dopamine can make you less motivated and excited about things. In Parkinson's disease, there is not enough dopamine in the areas of the brain important for movement. This leads to problems with muscle stiffness and movements such as walking.

The symptoms of a dopamine imbalance depend on what is causing the problem. They include physical symptoms such as:

• muscle cramps, spasms or stiffness
• digestion problems, such as constipation or reflux
• pneumonia
• trouble sleeping
• moving or speaking more slowly than usual

• feeling tired and unmotivated, or sad and lacking hope
• having low libido (sex drive)
• hallucinations (experiencing something that's not real)

How Can I Adjust My Dopamine Levels?

Adjusting dopamine levels is complicated, as it is involved in many different roles in the brain. Your doctor won't measure your dopamine levels directly, and there is no simple test to measure it. Your symptoms will be the clues that tell your doctor if you have too much or not enough dopamine. They will then prescribe medicines to adjust your dopamine level, based on your symptoms, and make adjustments based on how your body responds and how you feel.

The increasing popularity of GLP-1 medications is making its way onto college campuses, where young women face growing pressure to meet ideals of thinness and beauty.

Media reports suggest that the use of GLP-1 drugs, including semaglutide (Ozempic and Wegovy) and tirzepatide (Mounjaro and Zepbound), is rising among young women, including those with normal BMIs, seeking to achieve a thinner appearance.

Originally developed to treat type 2 diabetes, with some also approved for weight management, these medications can be highly effective but require a prescription and appropriate medical monitoring. Using them without a medical indication may expose people to unnecessary health risks, an expert warned.

Jay Campbell, a longevity and peptide expert and bestselling author, said

that while these drugs were developed to address metabolic conditions, they have been “hijacked as a cosmetic shortcut.”

“For someone who's metabolically dysregulated, they are a genuine medical intervention,” he told Fox News Digital. “But to a 20-year-old sorority member with a normal BMI, they look like an aesthetic hack in a syringe.”

A 2024 analysis published in JAMA found that 162,439 young adults ages 18 to 25 received at least one dispensed GLP-1 prescription in 2023.

Women accounted for 76.4% of these patients, although the analysis included medications prescribed for both diabetes and weight management.

Separately, the 2025 Monitoring the Future survey found that 2% of students in grades 8, 10 and 12 reported using a prescription GLP-1 medication, while another 2% said they had used one without a prescription.

Sororities can amplify pressure to maintain a certain appearance, with social media and comparisons among members potentially encouraging interest in GLP-1 drugs. Campbell said rapid, visible weight loss can quickly become a talking point within sorority houses, prompting other young women to consider the drugs as a shortcut to achieving a thinner look, including those with normal BMIs.

Risks of Using GLP-1 Drugs for Cosmetic Weight Loss

College-aged women may already be vulnerable to body-image pressures, Campbell noted, and social media can intensify those concerns.

GLP-1 medications can offer substantial benefits to eligible patients. In clinical studies of people taking these medications for obesity, fat mass generally accounts for more of the weight lost than lean mass, Campbell pointed out.

“The peptide isn't catabolic by itself – the real risk is that a healthy 20-year-old who isn't obese has far less metabolic and muscular reserve to lose from in the first place.”

When a young woman loses weight rapidly without consuming enough protein or doing resistance training, she may lose a greater proportion of lean mass, Campbell warned. Rapid weight loss can also contribute to facial and body changes sometimes referred to as “Ozempic face” and “Ozempic body.”

5 Things To Know Before Using GLP-1 Drugs

1. Check if you need them: Consult a doctor to determine whether GLP-1 treatment is medically appropriate.
2. Protect muscle mass: Eat enough protein and include resistance training to help preserve muscle during weight loss.
3. Understand pregnancy risks: Semaglutide labeling advises stopping Wegovy at least two months before a planned pregnancy. Tirzepatide can reduce oral contraceptive effectiveness for four weeks after starting treatment and after each dose increase.
4. Monitor mental health: Discuss any history of eating disorders, anxiety or depression with your prescriber and report worsening symptoms.
5. Consider long-term safety: Discuss potential risks, side effects and ongoing monitoring with a qualified doctor before starting treatment.

An unexplained blood clot could sometimes be the first warning sign of underlying cancer. In such cases, doctors investigate beyond the immediate causes of thrombosis.

While blood clots are mostly caused after surgery, prolonged immobility and other risk factors, a clot that develops without a known trigger may need a closer look, especially in older adults or patients with other certain concerning symptoms.

On World Thrombosis Day, observed on October 13, experts talk about the importance of recognising unusual clotting patterns and investigating underlying conditions without subjecting every patient to unnecessary tests.

“Sometimes an unexplained blood clot is the first clinical sign of an underlying cancer,” Dr Rahul Bhargava, Principal Director and Chief of Hematology, Hemato Oncology and Bone Marrow Transplant at Fortis Memorial Research Institute (FMRI), Gurugram told HealthandMe.

Can Cancer Trigger Blood Clots?

Cancer can interfere with the body's normal clotting mechanisms. Dr Bhargava explained, “Some tumors are able to activate the body’s clotting system by releasing substances such as tissue factor, which stimulates the production of thrombin and fibrin, the proteins involved in clot formation.”

He added that inflammation related to cancer and changes to blood vessels contribute to hypercoagulability, a condition in which the blood has an increased tendency to clot. In some patients, a tumour may also compress blood vessels, slowing blood flow. Cancer treatments, including surgery and certain chemotherapy drugs, can further increase the risk.

Dr Narendra Agrawal, Senior Consultant and Unit Head of Haemato-Oncology at Rajiv Gandhi Cancer Institute and Research Centre, explained to us that the body's natural anticoagulants help maintain blood in a liquid state. When these protective mechanisms are deficient, whether due to congenital mutations or other reasons, the risk of clotting can increase.

“When cancer is present in the body, it acts as a major driver of abnormal clotting within the vessels, making an unprovoked clot a critical clinical indicator that a malignancy may be forming,” he said.

However, an unexplained clot does not necessarily mean a person has cancer. Doctors must evaluate the patient's symptoms, medical history and other risk factors before deciding whether investigations are warranted.

Key Warning Signs

The absence of a clear trigger is a red flag that should not be ignored. Doctors typically look for common causes like recent surgery, trauma, prolonged immobility or long-distance travel before investigating other possibilities.

Dr Bhargava said concern increases when thrombosis occurs without an identifiable cause, particularly in older adults, or when a clot recurs despite adequate treatment. Other warning signs include unexplained weight loss, chronic fatigue, poor appetite, bleeding and changes in bowel movements.

“There is no particular symptom which will allow to distinguish cancer-associated thrombosis from others,” he cautioned, emphasising the need for a comprehensive clinical assessment rather than assuming that every unexplained clot indicates malignancy.

Dr Agrawal also highlighted specific findings that may prompt further investigation. “We suspect an underlying cancer when we encounter specific red flags,” he said, referring to unprovoked clots in older patients and physical findings like lumps, non-healing ulcers, recurring abdominal pain or blood in the stool.

Abnormal blood counts can provide additional clues. Changes in haemoglobin, white blood cell counts or platelet levels may lead doctors to investigate possible blood-related cancers or other underlying conditions.

Cancers Linked With Unexplained Blood Clots

Certain cancers come with a greater risk of venous thromboembolism, which includes deep vein thrombosis (DVT) and pulmonary embolism (PE).

“Certain cancers that predispose one to venous thromboembolism include pancreatic, lung, stomach, colorectal and ovarian cancers. Others include some forms of blood cancers,” Dr Bhargava said.

He explained that the risk varies according to the type and stage of cancer and the treatment involved. In some patients, an unprovoked clot may develop before the cancer itself is diagnosed.

The location of the clot can also influence how symptoms appear. DVT commonly affects the deep veins of the legs, causing swelling, pain and tenderness. When a clot travels to the lungs and causes a pulmonary embolism, symptoms may include chest pain and breathlessness.

Dr Agrawal said that clots in abdominal veins may cause abdominal pain, liver dysfunction, an enlarged spleen or intestinal bleeding. Clots affecting blood vessels in the brain or central nervous system may produce neurological symptoms, including paralysis. However, the location of a clot alone cannot prove if cancer is present.

What Investigations Are Recommended?

Doctors generally begin with a detailed medical history, physical examination and blood tests. These may include a complete blood count and assessments of kidney and liver function. Further testing depends on the clinical findings. Imaging or endoscopy may be recommended when symptoms, examination findings or blood abnormalities raise suspicion of an underlying malignancy.

Dr Bhargava cautioned against automatically subjecting every patient with unexplained thrombosis to extensive testing. “It is not always necessary to perform extensive imaging of the whole body or tumour marker testing in every patient with a clot that is unexplained and does not have any other worrying signs,” he said.

The aim is to identify cancers that warrant further investigation while avoiding unnecessary radiation exposure and incidental findings.

Dr Agrawal said doctors may use CT scans to look for hidden tumours, with MRI or PET scans considered for specific cancer evaluations. The extent of testing depends on factors such as the patient's age, clinical presentation, blood counts and physical examination findings.

When a patient has both cancer and thrombosis, doctors must manage the clot while navigating cancer treatment and the patient's risk of bleeding. “Anticoagulants are usually administered to prevent the expansion of the existing clot and the occurrence of other clots,” Dr Bhargava said.

The choice of medication, including a direct oral anticoagulant or low molecular weight heparin, depends on the patient's condition. Factors include kidney function, the possibility of gastrointestinal or urinary bleeding, drug interactions and the type of cancer treatment being administered.

Dr Bhargava explained that doctors must also consider platelet counts, planned or recent surgery, chemotherapy-related complications and active bleeding. The duration of anticoagulation is individualised and may extend beyond three to six months while the cancer and its treatment continue to pose a risk.

Menopause is not just the end of fertility or a gradual part of aging. It may trigger an abrupt, and rapid, “cliff-like” biological shift across multiple body systems, including the bones, liver and blood fats, a study has found.

Menopause is a natural stage of aging that ends menstruation and reproductive function. It usually occurs between ages 45 and 55.

It marks the permanent end of menstruation as ovarian follicles are depleted, leading to changes in several sex hormones. The research, published in Nature Medicine, found that some hormonal changes begin more than a decade before the final menstrual period.

The findings suggest that menopause is a distinct, body-wide physiological transition rather than simply a gradual part of aging. Comparable changes were not observed in men, prompting the researchers to describe the transition as a step-like physiological “cliff.”

Dr. Mia Schaumberg, an associate professor of physiology at the University of the Sunshine Coast, said the findings revealed a large “jump,” or change, at menopause that appeared like a “cliff” or “step” and progressed beyond “normal” aging, as represented by the male cohort.

What Did The Study Find?

Menopause has been linked to changes across multiple biological systems. However, establishing when these changes occur has been difficult because the final menstrual period is rarely recorded and long-term studies are relatively small.

To investigate these changes, a team at the Weizmann Institute of Science in Israel developed a computational method to reconstruct physiological changes around the final menstrual period.

The researchers analyzed more than 300 million laboratory tests from over 1 million women in the United States and Israel, covering the period from 1999 to 2024.

Across both datasets, the researchers observed abrupt changes in multiple body systems around menopause. In the US dataset, 52 of 90 laboratory tests showed statistically significant abrupt changes. These included measurements related to sex hormones, bone health, liver and kidney function, blood chemistry and blood fats.

Hormonal Changes Begin Over A Decade Early

The study found that three sex hormones began changing rapidly more than a decade before the final menstrual period:

• Anti-Müllerian hormone (AMH): Declined rapidly around 15 years beforehand.
• Follicle-stimulating hormone (FSH): Increased rapidly around 14 years beforehand.
• Estradiol: Changed around 12 years beforehand.

These findings suggest that hormonal changes associated with menopause begin much earlier than the final menstrual period and may precede broader physiological changes.

How Does Menopause Affect Bones, Liver And Kidneys?

The physiological changes were not limited to sex hormones such as estrogen. They were also detected in laboratory tests reflecting the function of other bodily systems, including the bones and kidneys.

“The postmenopausal results pointed toward poorer health outcomes,” Dr. Schaumberg said.

The researchers noted that the systems showing the most significant changes, including bone health and the liver, are particularly sensitive to estrogen. In contrast, systems with weaker known links to estrogen did not show detectable changes of the same kind.

Why Experts Disagree?

Australian experts urge caution interpreting the results. Martha Hickey, head of menopause services at The Women's Hospital Victoria who was not involved in the study, described the claim of "cliff-like" changes across multiple body systems as "unnecessarily alarming" for women.

"Physiological cliff is not a scientific or medical term," she told ABC News.

Sydney-based general practitioner Elina Safro, who chairs the education subcommittee of the Australasian Menopause Society, also agreed.

"My reading is that the 'cliff' theory is not plausible," she said.

Can Menopausal Hormone Therapy Help?

The study found that menopausal hormone therapy (MHT), also called hormone replacement therapy (HRT) and replaces estrogen and progesterone, was associated with smaller changes in several measures, particularly those related to bone, liver and kidney function.

The authors suggested that this finding could indicate a protective effect of MHT on certain bodily systems, including the skeletal system. But more research is needed to establish it.
