Lifestyle Medicine: Weight, Sleep, Alcohol, Smoking and Wellbeing
Lifestyle medicine should not feel like a lecture. Most people already know that sleep, movement, food, alcohol, smoking and stress matter. The harder part is making changes in real life when work, family, mood, pain, hormones, money, time and habits are all involved. A GP can help turn broad advice into a safer, more practical plan.
Why this matters
Dr Amanda Henderson takes a holistic view of health and can help with general lifestyle and wellbeing, including weight loss counselling, quitting smoking, reducing alcohol and drug harms, improving sleep and general wellbeing. In practice, this should be collaborative and non-judgemental. Shame rarely produces lasting health change.
A few helpful terms
· Behaviour change: Building specific, repeatable habits rather than relying only on motivation.
· Sleep apnoea: Interrupted breathing during sleep, often linked with snoring, tiredness and cardiometabolic risk.
· Harm reduction: Reducing health risk even when a person is not ready or able to stop a behaviour completely.
Common reasons to book a GP appointment
· You want help with weight without crash dieting.
· Sleep is poor and affecting mood, energy or concentration.
· Alcohol, smoking or vaping has crept up and you want support to cut down or quit.
· Stress, burnout or low mood is affecting your health habits.
· You want to reduce heart, diabetes, liver, cancer or mental health risk.
What we can talk through together
A GP can screen for medical contributors such as thyroid disease, sleep apnoea, depression, anxiety, medication effects, menopause, chronic pain or metabolic risk. They can help set priorities, arrange blood tests when indicated, discuss smoking cessation medicines, alcohol supports, sleep strategies, exercise plans, nutrition referral, psychology, medications for weight management in selected patients, or specialist referral when appropriate.
What to expect at the appointment
The first visit should focus on your goals and barriers. A plan that sounds impressive but cannot fit into your week is not a good plan. Small changes can be powerful when they are specific, repeatable and reviewed. Follow-up matters because behaviour change is rarely a straight line.
How to prepare
Think about what you most want to change and what has made it difficult before. Bring medications, supplements and any recent blood tests. If alcohol is a concern, write down a typical week honestly; this is for safety, not judgement.

Common questions
Can a GP prescribe medication for quitting smoking?
Often yes, depending on your history and suitability. Behavioural support and follow-up increase the chance of success.
Is weight always just about calories?
No. Sleep, hormones, medications, mental health, pain, environment, genetics and life stress can all affect weight.
Can alcohol affect sleep even if it helps me fall asleep?
Yes. Alcohol can fragment sleep and worsen snoring, reflux, mood and blood pressure.
Do I need a perfect plan?
No. A realistic plan that you can repeat is more useful than a perfect plan that lasts four days.
