Nausea is a common and debilitating symptom that affects millions of people worldwide. It is a subjective feeling of discomfort or unease in the stomach, often accompanied by a sensation of queasiness or vomiting. Nausea can be acute or chronic, and its causes can range from mild to life-threatening. In this article, we will provide a comprehensive review of nausea, including its causes, symptoms, diagnosis, and treatment options.
Causes of Nausea
Nausea can be caused by a wide range of factors, including:
1. Gastrointestinal Disorders: Conditions such as gastroesophageal reflux disease (GERD), irritable bowel syndrome (IBS), and inflammatory bowel disease (IBD) can cause nausea.
2. Infections: Viral, bacterial, and parasitic infections, such as food poisoning, stomach flu, and malaria, can cause nausea.
3. Medications: Certain medications, such as antibiotics, painkillers, and chemotherapy, can cause nausea as a side effect.
4. Hormonal Changes: Hormonal fluctuations during pregnancy, menstruation, and menopause can cause nausea.
5. Motion Sickness: Travelling by car, boat, or plane can cause motion sickness, leading to nausea.
6. Anxiety and Stress: Anxiety and stress can cause nausea, especially in people with a history of anxiety disorders.
7. Neurological Disorders: Conditions such as migraines, multiple sclerosis, and Parkinson’s disease can cause nausea.
8. Cancer and Chemotherapy: Cancer and chemotherapy can cause nausea, especially in the first few days after treatment.
Symptoms of Nausea
The symptoms of nausea can vary from person to person, but common symptoms include:
1. Feeling of Queasiness: A feeling of unease or discomfort in the stomach.
2. Vomiting: Forceful expulsion of stomach contents.

6. Fatigue: Feeling tired or weak.
7. Headaches: Headaches can occur due to dehydration or stress.
Diagnosis of Nausea
Diagnosing nausea can be challenging, as it can be caused by a wide range of factors. A healthcare professional will typically:
1. Take a medical history: Ask questions about symptoms, medical history, and lifestyle.
2. Perform a physical exam: Check for signs of dehydration, abdominal tenderness, and other physical symptoms.
3. Order diagnostic tests: Run tests to rule out underlying conditions, such as blood tests, imaging studies, or endoscopy.
Treatment options for nausea
Treatment options for nausea depend on the underlying cause, but common treatments include:
1. Medications: Anti-nausea medications, such as ondansetron, metoclopramide, or promethazine.
2. Lifestyle Changes: Avoiding triggers, eating small meals, staying hydrated, and getting plenty of rest.
3. Alternative Therapies: Acupuncture, acupressure, or herbal remedies, such as ginger or peppermint oil.
4. Dietary Changes: Avoiding spicy, fatty, or heavy foods, and eating bland foods, such as crackers or toast.
Conclusion
Nausea is a common and debilitating symptom that can be caused by a wide range of factors. Understanding the causes, symptoms, diagnosis, and treatment options for nausea can help healthcare professionals provide effective care and relief for patients. By recognising the complexity of nausea and taking a comprehensive approach to diagnosis and treatment, we can improve patient outcomes and quality of life.

Harsh soaps, pills harmful to children’s skin — Public Health Nurse

A disturbing practice in which some mothers and caregivers use skin-lightening creams, harsh soaps and even pills on children in an attempt to make their skin lighter has come under strong criticism from a public health nurse.
Mr Jonathan Kwame Quarshie, a Public Health Nurse at the Ho Teaching Hospital, has cautioned mothers and caregivers to desist from bleaching the skin of children, describing the practice as unnecessary and potentially harmful to their health.
He said it was worrying that some caregivers were exposing children to cosmetic products meant to alter their natural complexion, despite the delicate nature of children’s skin.
According to him, the situation becomes even more concerning when pills or tablets are given to children with the promise that the products would make their skin lighter “from within”.
“There is no justification for giving a baby or child an unprescribed substance for cosmetic purposes,” he cautioned.
Mr Quarshie stressed that “a baby is not a beauty project” and urged parents to appreciate and protect the natural complexion of their children rather than trying to change it to conform to perceived standards of beauty.
He explained that children’s skin was delicate and could be adversely affected by inappropriate cosmetic products, particularly those containing potentially harmful substances.
Some skin-lightening products may contain substances such as mercury, hydroquinone or potent corticosteroids, which could cause skin irritation, damage and other health complications depending on the substance and level of exposure, he said.
Of particular concern, he said, was mercury exposure, which could affect the nervous system and kidneys.
He therefore warned parents against treating children as “laboratories for beauty experiments” and urged them to consider the long-term health implications of exposing children to unnecessary chemicals and medicines.
Mr Quarshie said children did not need to have lighter skin to be considered beautiful, adding that what they needed was love, acceptance, proper nutrition, safe, age-appropriate skincare and appropriate medical care when necessary.
He advised parents whose children had skin conditions, unusual pigmentation, persistent rashes or other skin concerns to consult qualified health professionals rather than attempting to lighten or treat their skin with unprescribed products.
He also urged caregivers who had already used skin-lightening products on their children to stop further use and seek medical advice, particularly where a child developed irritation, swelling, skin thinning, changes in skin colour or other unusual symptoms.
He said it was worrying that children, particularly girls, were increasingly facing pressure to conform to certain standards of beauty from an early age.
He appealed to parents and families to create an environment in which children would grow up appreciating their natural appearance and understanding that their skin colour was not a problem that needed to be corrected.
“Every shade deserves protection. Every child deserves safe care,” he said, urging society to focus on protecting the health, dignity and wellbeing of children rather than changing their natural complexion.
He said children needed protection, not bleaching.

Drop in prices of foodstuff …traders ‘chase’ buyers

TRADERS of foodstuffs such as tomatoes, cassava, plantain and pepper are overwhelmed by the significant drop in prices across various markets and are urging customers to visit the markets to buy.
The development has come as a big relief to families who visit the markets for these essential ingredients used in daily food preparation.
When The Spectator visited markets around Accra Central, Agbogbloshie and Kingsway, among others, tomatoes had flooded every inch of space and were being sold at very affordable prices.
The situation was the same for other foodstuffs, including plantain, cassava and pepper.
The items were being sold at affordable prices as traders chased buyers.
Interacting with some traders, they said the abundance of foodstuffs had increased patronage at the various markets, with customers buying in large quantities.
With a budget of GH¢300, they claimed, one could buy enough foodstuffs to feed a family at home.
A trader, Esther Nyarko, told The Spectator that prices had reduced significantly and advised members of the public to buy in large quantities for storage.

“Cassava, for instance, can be cut into pieces and stored in a freezer. It can also be ground and processed into powder. In the same way, other foodstuffs can be stored in freezers so that when the season ends, people will have some to fall back on,” she said.
According to the traders, the current abundance of seasonal foodstuffs would not last forever, adding that scarcity could follow the harvest period.


Rose Nyarko, a trader at Agbogbloshie Market, said the abundance of tomatoes, pepper, onions and other vegetables was encouraging, adding that the lower prices were prompting customers to buy more.
Ms Anita Abban, a market woman at Kingsway, said farmers deserved commendation for making the foodstuffs available. She urged the government to support storage and transportation to prevent produce from going to waste.
A third trader, Maame Akua, told The Spectator that the development, coming after a period of vegetable scarcity, had brought joy to many people. She added that consumers were buying more than they needed in order to store some for future use.
A customer, Aunty Esi, said, “I came to buy foodstuffs for my family. I was surprised by the quantity available. There is no shortage, so I believe consumers should take advantage of the situation.”
Ms Rebecca Kumi said the variety of foodstuffs available was encouraging.
“The variety is good. You can find plantain, cassava, yam, tomatoes, pepper and other foodstuffs in large quantities. It makes shopping easier, and they are cheap. I wish it remains so for a long time,” she said.
