IELTS Health Essay Topics: The Question Type Matters More Than the Subject

Health is one of the most common Task 2 subject areas, and almost every page about it is a list of prompts. The list is the least useful part. The same health subject can arrive as an opinion essay, a problem and solution, a discussion or a two part question, and the question type decides your structure while the subject decides almost nothing.

This page sorts real health prompts by question type, shows what each type asks you to build, and then deals with the advice that follows every topic list: memorise health vocabulary. The published band descriptors do not ask for it.

The four shapes a health question arrives in

Read the prompt for its instruction, not its subject. Two health prompts from Bandly's sample library make the point.

Obesity rates among adults are rising in many countries. What are the causes of this problem, and what measures could be taken to address it?

Some governments have introduced a tax on foods that are high in sugar and fat in order to improve public health. To what extent do you think this is an effective measure?

Both are about diet and public health. The first needs causes matched to measures. The second needs a position on one named policy. If you prepared "health vocabulary" you have the same words for both, and you still do not know what either answer looks like.

Here is the mapping, with a health prompt for each type.

The instruction words are the whole signal: to what extent, what measures, discuss both views, and a prompt holding two question marks. Our post on reading a Task 2 statement covers that first thirty seconds in detail, and it applies to every subject, not just health.

Why matching the type matters more than the subject

The reason is in the Task Response descriptor, which is the criterion the question type lives in. Here is the band 7 bullet:

addresses all parts of the task

And band 5:

addresses the task only partially; the format may be inappropriate in places

Nothing in either bullet refers to the subject. What is being judged is whether you answered the question that was asked. A beautifully written essay about the causes of obesity, submitted in answer to a prompt that asked whether a sugar tax works, addresses the task only partially, because it answered a different question. Subject knowledge cannot rescue that, and the shortfall is in the criterion worth a quarter of your writing mark.

That is why the list of prompts on most pages is the wrong thing to study. Sort the same prompts by type and the list becomes practice at recognition, which is the skill actually being tested.

The advice this page disagrees with

Every health topic list ends with vocabulary to memorise: sedentary lifestyle, preventative healthcare, life expectancy, public health infrastructure. The implied promise is that producing these phrases raises your Lexical Resource band.

Read what the criterion actually asks for. Band 7 Lexical Resource:

uses a sufficient range of vocabulary to allow some flexibility and precision

uses less common lexical items with some awareness of style and collocation

And band 6:

uses an adequate range of vocabulary for the task

attempts to use less common vocabulary but with some inaccuracy

The words are range, flexibility, precision, collocation, accuracy. Not topic terminology. Not subject knowledge. A memorised phrase helps only if it is accurate and it fits; the band 6 bullet names the failure mode directly, an attempt at less common vocabulary with some inaccuracy, and that is what a half-remembered phrase produces. "Sedentary lifestyle" used correctly is worth something. "Sedimentary lifestyle", which candidates really do write, is worth less than "people who do not move much", because it is an error in a sentence that was trying to show off.

Neither does any criterion reward being right about the facts. No bullet in Task Response, Coherence and Cohesion, Lexical Resource or Grammatical Range and Accuracy mentions factual accuracy or statistics. The band 8 Task Response bullet asks for ideas that are relevant, extended and supported, and support means an explanation or an example, not a number. So inventing "studies show that 73% of adults" buys nothing it could not get from "many adults in my own country", and it carries a risk that the invented figure reads as padding.

What the two health answers in the library did

Bandly's library has two published Task 2 answers on health subjects. Both were estimated at an overall 7.0, and both had Lexical Resource as their weakest criterion at 6.

How this was counted: the two records in data/samples whose prompt category is health, with the four criterion bands and the overall estimate read from the record. Two answers is a very small set, and these are Bandly's own estimates rather than examiner marks.

Widen it and the pattern holds. Across all twenty five published samples, Lexical Resource is the weakest or joint weakest criterion in twenty three of them. Across the seventeen Task 2 answers alone it is weakest or joint weakest in fifteen. Vocabulary is the binding constraint on these answers, but it is binding on general range and precision, which is the same for a health essay and an education essay. Preparing a health word list does not touch it. Our post on collocation and lexical resource covers what does.

A bank of health prompts, sorted by what they ask

Practise these as four exercises rather than as one list.

Opinion.

1. Prevention of illness is more important than treatment. Government funding should reflect this. To what extent do you agree or disagree?
2. A tax on foods high in sugar and fat is an effective way to improve public health. How far do you agree?
3. Employers should be responsible for the physical health of their staff. Do you agree?

Problem and solution.

1. Obesity rates among adults are rising in many countries. What are the causes, and what measures could address it?
2. Many people in cities do not get enough physical exercise. Why is this, and how could more activity be encouraged?
3. Mental health problems among young people are increasing in many countries. What are the reasons, and what can be done?

Discussion.

1. Some people think healthcare should be funded entirely by the government. Others believe individuals should pay through private insurance. Discuss both views and give your own opinion.
2. Some argue that elderly relatives should be cared for at home; others say care homes are better for them. Discuss both views.
3. Some believe doctors should spend more time on prevention; others say treating the sick must come first. Discuss both views and give your opinion.

Two part question.

1. Fewer people cook meals at home than in the past. Why is this happening, and what effect does it have on public health?
2. Many people work long hours. What are the health consequences, and who should be responsible for addressing them?

Notice that subject matter repeats across all four groups. Obesity appears as a problem and solution above and as an opinion question in the first group. That repetition is the lesson: the subject recycles, the instruction does not.

How to practise a subject area properly

Three steps, and only the third involves writing a whole essay.

1. Classify twenty prompts in ten minutes. Write only the type next to each. If you misread an instruction here, you would have misread it in the exam, and this costs you ten minutes rather than forty.
2. Plan two of them in five minutes each. A position plus two supporting ideas for the opinion one; named causes plus matched measures for the problem one. The five minute essay plan is the method, and matching each solution to a named cause is where most problem essays lose Task Response.
3. Write one in full, timed. One complete answer teaches you more than five plans, but only after the planning is quick enough to leave you thirty five minutes of writing.

Do that across two subject areas rather than ten. The transferable part is the structure, and it is identical for health, environment and technology questions. Those three pages exist because the subject vocabulary differs; the shapes in them do not.

Ideas that work on almost any health prompt

Not vocabulary, but reasoning you can adapt. Each of these is a because, which is what turns a stated idea into a supported one.

• Cost shifting. Prevention is cheaper than treatment because a condition caught early needs fewer appointments and less medication than one caught late.
• Time, not knowledge. People often know what a healthy diet is and still do not cook, because long working hours make convenience food the realistic option. This reframes a health question as a working conditions question, which is a sharper answer than blaming ignorance.
• Behaviour responds to price. A tax changes what people buy because price is the signal most shoppers act on, which is also the argument against it: the burden falls hardest on people with the least money.
• Access is uneven. A public campaign reaches people who already read health advice, so a measure can look successful in aggregate and change nothing for the group most at risk.

Each of those is two or three sentences in an essay: the claim, the mechanism, and one consequence. That is the band 7 Task Response bullet, which asks you to present, extend and support main ideas.

What to do today

Take the twenty prompts above, cover the subjects, and read only the instruction words. Sort them into the four types in under ten minutes. Then pick the one type you found hardest to recognise and plan two answers of that type, because recognition is the part that costs marks silently.

When you have written one in full, compare it against the Task 2 sample answers, where each answer shows its question type, its four criterion estimates and the sentences behind them, including the two health answers in the table above. Then paste your own into Bandly for an estimate of the four criteria and the sentences driving each one, which will tell you whether your health vocabulary was precise or merely present.
