The main cause of death globally is still heart disease. Heart attacks may occur suddenly without any warning signs. However, in the film industry, intense chest pain would be portrayed for a heart attack. In actuality, many patients have slight symptoms that go unnoticed until the time of their heart attack days or even weeks prior to that.

Heart attacks do not always announce themselves with dramatic chest pain. Often, they manifest in subtle, easy-to-dismiss ways. Recognizing these overlooked warning signs and taking proactive steps toward cardiovascular health can save lives. If you or someone you know experiences any of these symptoms, seeking immediate medical care is crucial. Prioritizing heart health today can help prevent life-threatening complications in the future.

Warning Sings of A Heart Attack

1. Discomfort Pressure in the Chest

One of the earliest and most common warning signs of an impending heart attack is pressure, tightness, or fullness in the chest. This pain is not typically sharp and sudden, like most people associate with a heart attack, but it can be intermittent, coming in waves, and lasting for several minutes before fading away. According to the American Heart Association, this is one of the red flags when accompanied by exertion. If you have persistent chest pressure, you should call emergency services immediately.

2. Pain Radiating to Other Parts of the Body

The well-known symptom of chest pain can also manifest discomfort related to a heart attack as pain radiating to other parts of the body. It is not unusual for people experiencing this kind of heart attack to report feeling pain in the shoulders, arms, back, neck, and even jaw. The vagus nerve is one that connects the heart to the brain, abdomen, and neck. The pain may be referred to these regions. In case you experience a sudden, unexplained pain in these regions, especially when exercising, seek a doctor's opinion.

3. Dizziness and Lightheadedness

Feeling dizziness upon standing up quickly or missing a meal is common, but unexplained dizziness often with chest pain or shortness of breath is the first sign of heart attack. Sudden hypotension can seriously decrease the blood supply to the brain and cause dizziness. Dizziness that does not go away on its own should not be ignored.

4. Unexplained Fatigue

It often happens that excessive tiredness, particularly in a busy lifestyle, is considered trivial, but ongoing fatigue, mostly in women, is a predictor of heart failure. According to some studies, extreme fatigue often starts a month before a heart attack, primarily in women. This is simply because the heart cannot pump well enough, leaving insufficient oxygen available to muscles and organs. Consult a healthcare professional if you become increasingly tired over time, yet are getting all the rest in the world.

5. Nausea, Indigestion, or Stomach Pain

Digestive problems like nausea, vomiting, or indigestion are often mistaken for acid reflux or food poisoning. However, these symptoms can also indicate reduced blood flow to the digestive tract, a common precursor to heart attacks. If you experience gastrointestinal distress alongside other symptoms like dizziness or chest discomfort, it's important to seek medical advice immediately.

6. Cold Sweats and Excessive Perspiration

Without apparent reason, a heart attack might be signaled by sudden sweating without any exercise or hot weather conditions. The heart's inability to function properly creates the body's "fight or flight" reaction, which means excessive sweating will occur. Be aware of your body and never ignore a cold sweat, particularly if it coincides with other symptoms.

7. Heart palpitations or irregular heartbeat

A racing or irregular heartbeat can be a normal reaction to stress or caffeine consumption. However, regular or unprovoked heart palpitations may indicate that the heart is under duress. If the heart is not getting enough oxygen-rich blood, it can start to beat irregularly. If you experience palpitations along with dizziness, chest pain, or shortness of breath, you should see a doctor right away.

8. Shortness of Breath

If suddenly climbing stairs or performing other everyday activities becomes a problem, then there may be a heart issue. Shortness of breath usually occurs with heart conditions because the circulation is not adequate and less oxygen is provided to the lungs. This symptom can occur either with or without chest pain and is an important indicator of the presence of underlying heart disease. If you find yourself experiencing sudden unexplained breathlessness, then seek a healthcare provider as soon as possible.

When to Seek Medical Attention

Early detection of these symptoms and early intervention can help avoid a life-threatening heart attack. You should visit a doctor if you feel the following symptoms:

• Symptoms induced by exertion and relieved by rest
• The simultaneous onset of several warning signs, including weakness, dizziness, and nausea
• Personal or family history of heart disease, hypertension, diabetes, or smoking

Preventing Heart Attacks: Proactive Steps for Heart Health

Although heart attacks may come out of nowhere, lifestyle plays an important role in reducing a patient's risk; here are some heart-healthy habits to consider:

Take on a Heart-Healthy Diet: Focus on consuming whole foods, lean proteins, healthy fats, and fiber-rich fruits and vegetables. Try to limit processed foods, saturated fats, and added sugars.

Stay Active: Engage in at least 30 minutes of moderate physical activity most days of the week to strengthen your heart and improve blood circulation.

Smoking. Smoking is probably the single largest risk factor for heart disease. If you are a smoker, quitting can easily be the single best thing you can do to improve your heart health.

Deal with Stress: Chronic stress leads to heart disease. Relaxed people through various relaxation techniques including yoga, meditation, and even deep breathing, have lesser stresses.

Regular health checks Monitor blood pressure, cholesterol levels, and blood sugar on a regular basis. The risk factors' early detection can help avoid serious complications.

Malaria is usually understood as a fever illness, with symptoms such as chills, sweating, body ache, weakness, and in severe cases, anemia or organ complications. But for women, especially in malaria-prone regions, its impact can be more layered.

It can disturb the body’s hormonal rhythm, worsen fatigue, complicate menstrual symptoms, and create confusion between infection-related pain and period-related discomfort. That is why malaria should not be seen only as a seasonal mosquito-borne disease, but also as a health concern that can affect women’s reproductive and menstrual well-being.

India has made strong progress against malaria. According to the Government of India, reported malaria cases fell from 11.6 lakh in 2015 to 2.27 lakh in 2023, a reduction of roughly 80%. Malaria-related deaths also declined from 384 to 83 in the same period, a fall of about 78%. This shows that prevention, testing, surveillance, and treatment have improved significantly.

At the same time, malaria has not disappeared. The risk remains higher in endemic, tribal, forested, and hard-to-reach areas, where mosquito exposure, delayed testing, limited access to care, and anemia can make the illness more difficult to manage.

How Malaria Dents Menstrual Health

The connection begins with the body’s stress response. Malaria infection does not remain limited to the bloodstream. Research on hormones in malaria shows that the infection can affect host metabolism and create hormonal imbalances, with changes influenced by parasite type, disease severity, immune response, age, sex, nutrition, and stage of infection.

The research notes that malaria can dysregulate the hypothalamic-pituitary-adrenal, thyroid, and gonadal axes, which are central to stress, metabolism, and reproductive hormone regulation.

For menstrual health, this matters because periods are not controlled by the uterus alone. They depend on coordination between the brain, ovaries, and hormones such as estrogen and progesterone. When the body is fighting malaria, that rhythm can be disturbed.

Fever, inflammation, poor appetite, weakness, anemia, and high physical stress can make periods late, lighter, heavier, or more exhausting than usual. In some women, premenstrual symptoms such as body ache, fatigue, abdominal discomfort, and mood changes may also feel worse because malaria itself produces overlapping symptoms.

There is also a direct hormonal pathway to consider. Cortisol, often called the stress hormone, is reported to rise in both P. falciparum and P. vivax malaria. High cortisol can affect immune function and may also disturb the wider hormonal balance on which regular ovulation and menstruation depend.

The same research notes that lower estradiol has been reported in severe falciparum malaria, while progesterone levels have also been reported to be lower in patients with P. falciparum malaria.

These findings do not mean every woman with malaria will have menstrual changes, but they do show that malaria can interfere with the hormonal systems linked to reproductive health.

Link Between Malaria And Anemia in Women

Anemia is another important link. Malaria can destroy red blood cells and contribute to severe anemia. Menstruation, especially heavy bleeding, can also lower iron stores. When both happen together, the result can be extreme tiredness, dizziness, breathlessness, paleness, poor concentration, and slower recovery.

This is particularly relevant in India, where anemia among women is already a major public health concern. A woman recovering from malaria who also has heavy periods should not dismiss prolonged weakness as “normal period fatigue.”

Malaria: Delayed Symptoms In Women

One reason diagnosis can be delayed is that malaria symptoms are often nonspecific. WHO lists fever, headache, and chills as common early symptoms, and says early testing is important because symptoms may initially resemble many other fever illnesses. In women, body ache, fatigue, abdominal discomfort, and weakness may be mistaken for PMS, a painful period, viral fever, or early pregnancy unless malaria is actively considered.

The risk is even more serious during pregnancy, including early pregnancy when a woman may not yet know she is pregnant. WHO states that malaria during pregnancy can cause premature delivery or low birth weight, and it is also noted that pregnancy reduces immunity to malaria, increasing the risk of severe anemia and illness.

The practical message is simple: if fever with chills, severe body ache, vomiting, unusual weakness, dizziness, or headache appears around the time of a period, it should not automatically be treated as PMS or “period weakness,” especially after travel to or residence in a malaria-prone area.

A malaria test should be done promptly, and treatment should be taken only under medical supervision.

Malaria can affect menstrual health by placing stress on the body’s blood, hormones, immunity, and energy reserves. For women, recognizing this connection can help prevent delayed diagnosis and support faster recovery.

When it comes to gas, bloating, and "acidity," it is easy to think that these are simply a case of IBS or nervousness about eating. However, gastric cancer is one of the most frequent causes of cancer-related deaths in the world, including in India, where it is a common form of gastrointestinal cancer. In some cases of early gastric cancer, the symptoms are so similar to other digestive troubles that it could prove fatal to ignore the warning signs.

In an interaction with Health and Me, Dr Rakesh Kumar Sharma, Senior Consultant Medical Oncologist at M | O | C Cancer Care & Research Centre, Gurugram, spoke about the symptoms of stomach cancer and how it can often be confused with IBS.

Why is IBS confused with stomach cancer?

IBS is a functional gastrointestinal condition, which means the patient’s gut may seem fine, but it is not functioning properly. Common complaints in IBS include abdominal pain, bloating, diarrhoea, and constipation. Patients may notice a pattern in which their symptoms come and go over several months and may even associate them with food triggers or emotional stress.

However, IBS does not cause ulcers, bleeding, or intestinal damage, and patients have no greater likelihood of developing cancer when evaluated properly. This means that since many symptoms of IBS, inflammation, and cancers can overlap, there is a risk of diagnosing something serious as “just IBS."

What are the symptoms of stomach cancer?

Stomach cancer commonly begins in the inner lining of the stomach and usually presents with non-specific and subtle symptoms in its early stages. Common complaints include continuous indigestion and heartburn that fail to respond to common anti-acidity medication. Early satiety is another common complaint, whereby patients feel full too soon during meals, along with upper abdominal discomfort and heaviness. Other common symptoms include bloating, nausea, and gradual loss of appetite over weeks.

It is important to differentiate early-stage gastric cancer from simple acidity and IBS, since the latter conditions usually show periodic improvement and respond to common medications. However, if the above symptoms persist for two to three weeks without relief despite basic management, further evaluation may be required, especially in middle-aged and older patients.

Stomach cancer symptoms to never miss

There are certain symptoms that should never be overlooked and are regarded as red flags requiring prompt investigation for possible stomach cancer:

1. Sudden weight loss and poor appetite
2. Concurrent vomiting and regurgitation
3. Dysphagia or difficulty swallowing
4. Melena or hematochezia
5. Anaemia (reduced haemoglobin level), tiredness, and weakness due to chronic blood loss
6. Ongoing or progressive upper abdominal pain or a lump in the upper part of the abdomen

Any of these require immediate attention, regardless of an IBS diagnosis.

Who is at an increased risk?

Persistent infection by the bacterium Helicobacter pylori is the most well-established risk factor for the development of stomach cancer, primarily lower stomach cancers. H. pylori infections affect about half the global population and may lead to chronic inflammation, ulcers, and eventually precancerous changes in the stomach lining. High dietary consumption of salt, pickled or smoked foods, and processed meats increases the risk, especially when there is an existing H. pylori infection.

Smoking and alcohol abuse independently contribute to an increased risk of gastric cancer, along with obesity and specific genetic or familial risk factors. There are higher rates of gastric cancer in some parts of India, with the majority of cases being detected at later stages of the disease. This emphasises the importance of early detection and evaluation in populations with a high burden of gastric cancer.

When should you be alarmed?

You do not have to worry about every episode of acid reflux, but you should never dismiss anything unusual that occurs in your body. You need to consult your doctor if your indigestion, epigastric pain, early satiety, and bloating persist for two to three weeks even after conventional treatment. You experience alarming symptoms such as weight loss, vomiting, dysphagia, black stools, and anaemia

Fructose, found in all processed foods such as sodas and snacks, may not just be adding to your calories. A new study warns about its significant role in the rising metabolic diseases.

The study, published in the journal Nature Metabolism, showed that fructose may be playing a distinct role in driving metabolic disease, acting as a signal that promotes fat production and storage.

“Fructose is not just another calorie,” said lead author Richard Johnson, professor at the University of Colorado Anschutz.

“It acts as a metabolic signal that promotes fat production and storage in ways that differ fundamentally from glucose,” he added.

Why Fructose's Metabolic Effects Raise Concern?

In the study, the researchers examined how common dietary sweeteners, including table sugar (sucrose) and high-fructose corn syrup, impact human health.

While both contain glucose and fructose, fructose has unique metabolic effects that may more directly contribute to obesity and related conditions.

“Its metabolism bypasses normal energy regulation, leading to increased fat synthesis and lower cellular energy, processes linked to obesity, insulin resistance, and cardiovascular risk,” revealed the researchers.

As the body can produce fructose internally from glucose, the team pointed out that its impact on disease may be broader than just dietary sugar intake.

The study also outlined how fructose metabolism bypasses key regulatory steps in the body’s energy-processing pathways.

This can lead to

• increased fat synthesis,
• depletion of cellular energy (ATP)
• the production of compounds linked to metabolic dysfunction.

“This review highlights fructose as a central player in metabolic health,” said Johnson. “Understanding its unique biological effects is critical for developing more effective strategies to prevent and treat metabolic disease.”

How Much Sugar Is Too Much?

The World Health Organization (WHO) advises that added sugars must make up fewer than 10 per cent of your daily total energy intake, better yet, aiming for 5 per cent for optimal health gains—approximately 25 grams or 6 teaspoons a day for an adult eating 2,000 calories a day.

The American Heart Association (AHA) is even more stringent:

Women: Restrict to 100 calories/day of added sugars (approximately 25 grams or 6 teaspoons).

Men: Restrict to 150 calories/day (approximately 38 grams or 9 teaspoons).

You're taking in too much added sugar if:

• Over 10 per cent of your total daily calories are from sugar.
• You're taking in more than 150 calories/day (men), or 100 calories/day (women) from sugar.

While sugar in whole foods such as fruits and vegetables isn't the problem—it's part of a nutrient-dense package, the problem lies with the sneakily added sugars in everyday products such as ketchup, cereals, salad dressings, protein bars, and "health" drinks.

Instead of being afraid of all sugar, pay attention to where it's coming from. Read labels carefully. Stick to whole foods, avoid processed items. While natural sugars in your bowl of fruit or glass of milk may not be a problem, keep an eye out for the syrup in your coffee or that "healthy" granola.

Natural sugars can absolutely be part of a balanced, healthy diet. However, the body doesn’t distinguish between a sugar cube and a fruit smoothie when it comes to blood glucose spikes. What makes all the difference is the nutritional context.
