Seasonal flu or influenza is an acute respiratory infection caused by flu viruses which circulate in all parts of the world.

Seasonal flu symptoms include a high temperature, a severe (usually dry) cough, headache, muscle pain, joint pain, sore throat, and a runny nose. A person with the flu will also feel extremely unwell.

Most people recover from the symptoms within a week or two without requiring medical attention. But flu can cause severe illness or death especially in people at high risk (see below).

Illnesses range from mild to severe and even death. Hospitalisation and death occur mainly among high risk groups.

The most effective way to prevent the flu is get vaccinated. An annual vaccination is recommended as immunity decreases over time. The flu vaccine can be administered as an injection or using an intra-nasal spray.

While everyone should consider getting a flu vaccine, it is especially important that the following groups get vaccinated:

• Persons aged 65 years and older.
• Persons with a chronic illness requiring regular follow up, e.g. chronic respiratory disease (including chronic obstructive pulmonary disease, cystic fibrosis, moderate or severe asthma and bronchopulmonary dysplasia), chronic heart disease (including acute coronary syndrome), chronic renal disease, diabetes mellitus, haemoglobinopathies, chronic liver disease, chronic neurological disease (including multiple sclerosis, hereditary and degenerative disorders of the central nervous system).
• Those who are immunosuppressed due to disease or treatment including those with missing or non-functioning spleens.
• All cancer patients.
• Patients with any condition that can compromise respiratory function, e.g. spinal cord injury, seizure disorder or other neuromuscular disorder.
• Persons with Down syndrome.
• Those with morbid obesity, i.e. body mass index over 40.
• All pregnant women (vaccine can be given at any stage of pregnancy).
• Healthcare workers.
• Household contacts of at-risk persons.
• Out-of-home care givers to at-risk persons.
• Residents of nursing homes and other long stay institutions.
• Carers.
• People with regular contact with pigs, poultry, or waterfowl.

Nutrients are substances that are essential for good health - promoting energy, providing building blocks to form body structures, and helping to regulate body functions.

Protein, carbohydrate, and fat are classified as macronutrients providing energy to fuel the body plus protein is broken down into amino acids to repair and grow new muscle fibres.

Minerals and vitamins are classified as micronutrients and play a key role in the body's structures and functions.

The Irish government and the HSE publish detailed nutritional guidelines comprising a few key points:

• Eat more vegetables, salad, and fruit - Up to seven servings a day.
• Limit your intake of high fat, sugar, salt (HFSS) food and drinks.
• Reduce portion sizes and use the food pyramid as a guide.
• Increase your physical activity.

For many people, following a balanced and healthy diet coupled with exercise, will provide all the nutritional needs of your body.

However, nutritional needs vary with age, activity, and medication - particularly the long-term use of medications.

With age the lean body mass naturally reduces and there is an increase in body fat. This generally results in reduced mobility and subsequent risk of osteoporosis and falls.

It also reduces the metabolic rate causing the body's energy requirements to fall which may in turn may lessen your appetite. The reduced intake of foods may also decrease your micronutrient intake (for example vitamins).

Certain medications are well known for causing side effects such as nausea or drowsiness affecting nutritional intake, but sometimes a lesser known side effect happens without giving you any warning: nutrient deficiency.

Most medications for a short amount of time will not lead to nutrient deficiency.

But long-term use can be different - reducing the absorption of certain vitamins or depleting minerals in the body or even inhibiting the production of important enzymes.

Even commonly used medications like some statins, PPIs (for acid reflux) and diuretics (lower blood pressure) etc taken for long periods can lead to nutrient deficiency.

If you feel any of the above apply to you, we can complete a review of your medications and diet to provide guidance on what nutritional supplements would benefit you.

Every year in Ireland, nearly 6,000 people die because of smoking with many more suffering from smoking related diseases. The HSE estimates that 1,000 people are admitted to hospital every week with an illness caused by smoking.

In our pharmacy, we help smokers break nicotine addiction by recommending Nicotine Replacement Therapy (NRT). NRT comes in many different forms including patches and gums. It is important that the right option is chosen to suit individual needs.

Evidence has shown that if a smoker participates in a smoking cessation service that combines advice, support, and Nicotine Replacement Therapy that the smoker is 4 times more likely to quit compared to using willpower alone.
