Why Is It Called 'Morning Sickness' If It Can Occur At Other Times Of Day?

Updated Jan 3, 2025 | 06:00 AM IST

SummaryMorning sickness is influenced by hormonal shifts, particularly elevated hCG and progesterone levels. These changes, vital for pregnancy, can trigger nausea and vomiting, commonly in the first trimester but not limited to mornings.
Why Is It Called 'Morning Sickness' If It Can Occur At Other Times Of Day?

If you thought "morning sickness" was confined to sunrise, think again! Most pregnancy's popular label doesn't play by the clock, proving it's more than just an early-bird experience. Pregnancy is a journey filled with excitement, anticipation, and a fair share of challenges. Among these challenges is the phenomenon of morning sickness, a common experience for up to 80% of pregnant women. Characterized by nausea and vomiting, this condition often strikes in the early stages of pregnancy.

Despite its name, morning sickness is not limited to the morning, leading many to question why it is called such. This article explores the nuances of morning sickness, its causes, symptoms, and why it earned its misleading moniker.

What Is Morning Sickness?

Morning sickness is a condition characterized by nausea and vomiting that is usually present in pregnant women, especially in the first trimester. Even though it is often one of the earliest symptoms of pregnancy, it can continue all day. In most cases, symptoms abate during the second trimester, but for a small percentage of women, discomfort persists until delivery.

It is more common in women with multiple pregnancies, and its symptoms can range from mild to extreme. In some cases, the condition presents itself as hyperemesis gravidarum, an extreme condition requiring medical treatment.

Why Is It Called 'Morning' Sickness?

The name "morning sickness" originated from the fact that the condition is most active when waking up. This can be partly because of the physical changes a pregnant woman experiences during this time.

Low Blood Sugar: Blood sugar levels are usually at their lowest in the morning, and pregnancy exacerbates these drops because of the increased energy demands of the growing fetus.

Hormonal Fluctuations: The hormone human chorionic gonadotropin (hCG) peaks during early pregnancy and may stimulate nausea, particularly after periods of fasting, such as overnight.

Digestive Changes: Higher progesterone levels cause a relaxing effect in the stomach and intestines. Stomach acids begin to build up inside, leading to nausea. While this happens, "morning sickness" is somewhat of a misnomer since 2% of women actually say they have all symptoms confined strictly to the morning. Others call for it to be renamed to "all-day sickness.".

Interestingly, morning sickness may have an evolutionary purpose. Researchers theorize that it acts as a protective mechanism, steering pregnant women away from foods that could harm the developing fetus. Foods like raw eggs, poultry, and certain meats are often avoided due to their potential for contamination, which aligns with the aversions many women experience during pregnancy.

What Causes Morning Sickness?

The exact reason for morning sickness is unknown; however, several are thought to cause it:

Hormonal Changes

Hormonal changes and the high concentration of hCG and estrogen present during pregnancy result in nausea and vomiting. Thyroid Hormones The rapid change in thyroxine levels as caused by the increase in hCG can stimulate digestion and can increase symptoms of nausea. Hypoglycemia Low sugar levels in blood, especially post-fasting can worsen the nausea.

Genetics

A family history of morning sickness may predispose a woman to it. Symptoms of Morning Sickness Morning sickness usually manifests as:

Nausea with or without vomiting. Aversion to certain smells or foods. Symptoms are most severe in the first trimester but can last longer.

While typically tolerable, more severe forms may need to be treated by a doctor due to dehydration or substantial weight loss.

What Is Hyperemesis Gravidarum?

For fewer than 1% of pregnant women, morning sickness escalates into hyperemesis gravidarum, characterized by:

- Severe nausea and vomiting.

- Loss of more than 5% of pre-pregnancy body weight.

- Electrolyte imbalances.

It may need hospitalization for hydration and nutritional supplementation.

Other Possible Causes of Nausea and Vomiting in Pregnancy

Not all nausea and vomiting in pregnancy are caused by morning sickness. Other conditions that mimic its symptoms include: Gastroesophageal reflux disease (GERD). Thyroid disorders. Gallbladder disease. Appendicitis or pancreatitis. A proper diagnosis should be undertaken by a healthcare provider if the symptoms are not following the typical pattern of morning sickness.

How to Live with Morning Sickness

Even though morning sickness can't be avoided entirely, some remedies help ease symptoms:

Eating small, frequent meals to keep blood sugar stable

Avoiding foods and smells that cause a reaction

Staying hydrated with water and electrolyte-rich fluids

Taking ginger or vitamin B6 supplements as directed by a healthcare provider

When to See a Doctor

Medical doctors will be needed to give stronger anti-nausea drugs when needed for very serious cases. Though termed "morning sickness," most women get nausea throughout their pregnancies. There isn't clear consensus about its etiology; it's mostly known to result from hormonal fluctuations, low blood sugar, and perhaps a component of evolution.

Education about this illness and causes could better guide many pregnant women on how to make the phase as painless as possible.

Most morning sickness subsides as the pregnancy advances, and a healthier, more comfortable path to motherhood is opened up.

A new study suggests that drinking sugary drinks can increase anxiety, among other mental issues, in adolescents by 34 percent.

Sugary drinks are known to be more harmful due to their low fiber, protein, or fat, which typically slow down digestion in solid foods. This means liquid sugar gets into your bloodstream very quickly, causing a sudden jump in blood sugar and insulin levels.

Hyper-fast intake of such drinks can also make it hard for your liver to process the sugar, especially the fructose part. n large amounts, fructose turns into fat in your liver. This buildup of fat is linked to metabolic problems that lead to Type 2 diabetes.

Apart from this, a Bournemouth University, UK literature review analyzed people aged between ten and 19 who drank fizzy drinks, colas, sweetened fruit juices, sweetened milk drinks, energy drinks, and sweetened tea or coffee and found multiple links between the beverages and anxiety diagnosis.

The gut-brain axis — the connection between the brain and the gut — may help explain the link between sugary drinks and anxiety. But gut health is influenced by many factors, including diet, stress, and sleep, which are also linked to anxiety.

Overall, the study suggests that cutting back on sugary drinks could help support teenagers’ mental health. While many studies have looked at how reducing sugary drinks improves physical health, more research is needed to see if it also benefits mental health.

WHO Asks Countries To Tax Sugary Drinks

The World Health Organization is asking countries across the world to increase taxes on sugary drinks and alcohol to reduce cases of chronic conditions such as Type 2 diabetes, obesity, heart disease and fatty liver.

In a January 13 virtual conference, WHO Director-General Dr Tedros Adhanom Ghebreyesus said: "Health taxes have been shown to reduce consumption of these harmful products, helping to prevent disease and reduce the burden on health systems.

"At the same time, they generate an income stream that governments can use to invest in health, education and social protection."

According to a recent report on sugar-sweetened beverages taxes, at least 116 countries tax sugary drinks, including sodas or carbonated canned drinks, but other high-sugar products, such as 100 per cent fruit juices, sweetened milk drinks and ready-to-drink coffees and teas, escape taxation.

Additionally, another report on alcohol taxes shows that even though 167 countries levy taxes on liquor, wine and beer, alcohol has become more affordable or remained unchanged in price in most countries since 2022, as taxes do not get adjusted for inflation and income growth.

How To Cut Back On Sugary Drinks?

Sugary drinks can feel addictive. If you find yourself hooked, try to slowly reduce how much you drink, just like you would with alcohol or tobacco. It helps to plan ahead for when you usually crave a soda.

You can start by mixing plain sparkling water with an equal amount of fruit juice or soda. Then, week by week, slowly reduce the amount of the sugary drink until you're mostly just drinking sparkling water. If it helps, add a little lemon or lime juice for flavor.

Running Ultra-Marathons Harms Your Red Blood Cells, Study Says

Participating in ultra-marathons can cause damage to your red blood cells' flexibility and hamper their oxygen-carrying capacity, a study suggests.

A study published in the American Society of Hematology’s journal Blood Red Cells & Iron notes that extreme forms of exercise may harm, rather than support, overall health.

In the case of ultra-marathons, runners experience breakdown of normal red blood cells during races. Over time, their red blood cells become less flexible and potentially reduce their ability to efficiently carry oxygen, nutrients and waste products throughout the body.

Travis Nemkov, associate professor in the department of biochemistry and molecular genetics at the University of Colorado Anschutz and the study’s lead author said of the results: “Participating in events like these can cause general inflammation in the body and damage red blood cells.

“Based on these data, we don’t have guidance as to whether people should or should not participate in these types of events; what we can say is, when they do, that persistent stress is damaging the most abundant cell in the body.”

Red blood cells transport oxygen and waste throughout the body and must be flexible enough to squeeze through small blood vessels. When red blood cells become inflexible or rigid, they lose their ability to deform and navigate through the body's smallest vessels, leading to impaired oxygen delivery, blockage of blood flow, and rapid destruction by the body's filtration system.

This can lead to low hemoglobin and anemia which can pave the way for diseases like Sickle Cell Disease (SCD), thalassemia, hereditary spherocytosis, and, in some cases, the "storage lesion" of blood in transfusion banks.

What Is Low Hemoglobin?

Hemoglobin is the oxygen-carrying protein in red blood cells. Adequate hemoglobin levels are essential for keeping organs and tissues properly supplied with oxygen. Without enough of it, the body begins to struggle to meet its basic energy needs.

Low hemoglobin is usually identified through a blood test. It is most often measured as part of a complete blood count (CBC), which checks different components of the blood, including red and white blood cells and platelets, as per Healthline.

While exact reference ranges can vary slightly between laboratories, healthy adult hemoglobin levels usually fall within the ranges listed below. These values are different for babies, children, and teenagers:

  • Normal Hemoglobin Count in Grams per Deciliter (g/dL) | Normal Hemoglobin Count in Grams per Liter (g/L)
  • Adult Males: 13.8–17.2 | 138–172
  • Adult Females: 12.1–15.1 | 121–151

Any reading below these ranges in adults is considered low hemoglobin and suggests that oxygen delivery in the body may be reduced, as per Mayo Clinic.

Is Low Hemoglobin Ever Dangerous?

Low hemoglobin is not always an emergency. In many cases, it develops gradually and can be managed with treatment. That said, very low levels can be dangerous. A hemoglobin level below 5.0 g/dL has been linked to serious complications, including heart failure and even death. Levels under 6.5 g/dL may be considered life-threatening and require urgent medical care.

What Causes Low Hemoglobin?

One of the most common reasons for low hemoglobin is anemia. Anemia occurs when the body does not have enough healthy red blood cells. The most frequent type is iron-deficiency anemia, which develops when the body lacks enough iron to produce hemoglobin.

Other forms of anemia include pernicious anemia, which occurs when the body cannot properly absorb vitamin B12, and hemolytic anemia, where red blood cells are destroyed faster than they are produced.

Low hemoglobin can also be caused by:

  • Blood loss or internal bleeding
  • Certain cancers, including leukemia, lymphoma, multiple myeloma, and cancers that spread to the bone marrow
  • Chronic kidney disease
  • Deficiencies of folate or vitamin B12
  • Hypothyroidism
  • Liver disease
  • Poor nutrition or malnutrition
  • Myelodysplastic syndrome (MDS)
  • Sarcoidosis
  • Sickle cell disease and other inherited blood disorders
  • Systemic lupus erythematosus
  • Thalassemia, a genetic condition that reduces hemoglobin production
  • Excess fluid in the body
  • Cancer treatments such as chemotherapy and radiation can also lower hemoglobin levels, particularly in adults over the age of 65.

What Does Having Low Hemoglobin Feel Like?

Some people with mildly low hemoglobin may not notice any symptoms at first. Others may begin to feel unwell as levels drop further or remain low over time. Common signs and symptoms include:

  • Feeling dizzy or lightheaded, sometimes fainting
  • Muscle weakness
  • Ongoing fatigue or low energy
  • Pale or washed-out skin
  • Frequent headaches

How Is Low Hemoglobin Treated?

Treatment depends entirely on what is causing the low hemoglobin. A healthcare provider will first identify the underlying reason before recommending treatment. Possible treatment options include:

  • Blood transfusion: If hemoglobin is low due to heavy blood loss, a transfusion may be needed to restore levels quickly.
  • Vitamin supplements: When nutritional deficiencies are the cause, iron, folate, or vitamin B12 supplements are often prescribed. Hemoglobin levels usually begin to improve within six to eight weeks.
  • Intravenous (IV) therapy: In cases where iron or B12 levels need to be raised rapidly, IV infusions may be recommended.
  • Bone marrow transplant: This may be required when low hemoglobin is linked to certain cancers or bone marrow disorders.

If a long-term illness is responsible, managing that condition becomes the key part of treatment, alongside monitoring hemoglobin levels regularly.

Danish Study Links Hidden Bacteria In The Gut To Colorectal Cancer

Updated Mar 1, 2026 | 03:40 PM IST

Danish Study Links Hidden Bacteria In The Gut To Colorectal Cancer

Researchers from Denmark and Australia have discovered a new virus in the gut that can contribute to the development of colorectal cancer in the body, one of the leading causes of death in the world.

Using genetic sequencing, researchers studied the gut bacteria of cancer patients in a large Danish study and found that Bacteroides fragilis, an anaerobic, gram-negative, pleomorphic to rod-shaped bacterium, often carried a bacteriophage — a virus that infects and reproduces inside bacteria.

This allows it to produce a toxin (BFT) in the colon, promoting chronic inflammation, cell proliferation and tumor growth in the region.

People with colorectal cancer were twice as likely to have this bacteriophage in their gut bacteria. The virus also appears to be previously unknown and does not match any recorded type so far.

Although the first finding came from a small group, it was later confirmed in a larger study of 877 people with and without colorectal cancer. The results suggest that viruses hiding inside B. fragilis may play a role in cancer development.

Microbiologist Flemming Damgaard, from Odense University Hospital in Denmark: "It has been a paradox that we repeatedly find the same bacterium in connection with colorectal cancer, while at the same time it is a completely normal part of the gut in healthy people.

"We have discovered a virus that has not previously been described and which appears to be closely linked to the bacteria we find in patients with colorectal cancer."

What Is Colon Cancer?

Colon cancer develops from polyps in the colon or rectum, often taking years to show symptoms. The cancer begins when small growths called polyps form on the inner lining of the colon or rectum. Over time, changes in the DNA of these cells can cause the polyps to become cancerous.

As abnormal cells multiply, they replace healthy cells and eventually form a mass known as a tumor. This process develops slowly, often taking up to ten years for a precancerous polyp to turn into cancer and begin showing symptoms.

The American Cancer Society notes that colorectal cancer impacts around 1.9 million people every year.. In India, it is the fourth most common cancer among both men and women. In 2022, there were 64,863 new cases and 38,367 deaths.

Projections suggest that incidence will continue to rise by 2026, reflecting both lifestyle changes and improved detection.

Colon cancer can be difficult to detect because it often develops without obvious symptoms. According to experts , these are the three things you should do to protect yourself:

1. Timely risk screening

2. Knowing your cancer family history

3. Acting on early symptoms

What Early Symptoms Should You Look Out For?

Colon cancer rarely announces its presence with dramatic symptoms. More often, it whispers — through changes in bowel habits, subtle abdominal discomfort, or unexplained weight loss.

Some of the most commonly missed early signs include:

  • Persistent changes in bowel movements: Chronic constipation or diarrhea often dismissed as dietary effects.
  • Blood in stool: Bright red or dark blood should not be ignored.
  • Unexplained weight loss: Especially when unintentional.
  • Abdominal cramps or bloating: Misinterpreted as common digestive issues.

Persistent changes in bowel habits, especially if they last more than a few days, must be taken seriously. Narrow or ribbon-shaped stools may indicate a tumor partially blocking the colon.
