Stress, Diet, and Their Effects on Women’s Health

Stress, Diet, and Their Effects on Women’s Health

Author: Ng Qiao Wei, Registered Pharmacist

Quick answer

Chronic stress can affect women’s mood, sleep, digestion, appetite and menstrual patterns. Stress can also influence eating habits. Balanced meals, regular physical activity, adequate sleep, relaxation practices, and social or professional support can all help support overall well-being. No single food or supplement can “cure” stress; a consistent pattern of healthy habits may be more helpful. [3, 13–17]

In Malaysia, women may face stress from work, family responsibilities, caregiving and financial pressures. While short-term stress can sometimes be helpful, ongoing stress can affect both mental and physical health. [2, 3, 13–14]

How does chronic stress affect women’s health?

When stress continues for a long time, it can affect different aspects of health. Chronic stress may affect sleep, appetite, digestion, blood pressure, mood and reproductive health. [3, 13–14]

Menstrual and hormonal symptoms

Long-term stress may contribute to irregular periods and more noticeable premenstrual symptoms. It may also be associated with acne or other skin problems in some women. Polycystic Ovary Syndrome (PCOS) is a separate medical condition involving several contributing factors, so stress alone should not be assumed to cause it. New or ongoing irregular periods, or possible PCOS symptoms, should be discussed with a healthcare professional. [4, 13, 18]

Mood and mental health

Stress can make it harder to relax or concentrate and may contribute to anxiety, irritability or changes in mood. Women are also more likely than men to report some stress-related symptoms and to experience anxiety or depression. [2, 3, 13–14]

Digestion and gut symptoms

Stress can cause stomach upset and may worsen digestive symptoms such as gas and bloating, particularly in individuals with irritable bowel syndrome (IBS). It can also change appetite, leading some people to eat more and others to eat less. [3, 13–14]

Weight and heart health

Long-term stress can influence eating patterns and body weight, while high stress levels may also raise blood pressure. Managing stress is therefore one part of supporting overall health. [3, 13]

How can stress change the way you eat?

Have you noticed your eating habits changing when you feel overwhelmed? Stress can affect appetite, causing some people to eat more than usual while others may eat less. Research in women has also found an association between higher consumption of ultra-processed foods and poorer mental health outcomes. [5, 13–14]

A useful goal is to return to regular, balanced meals and adequate hydration. Paying attention to changes in your appetite and eating habits during stressful periods may also help you maintain a more regular eating pattern. [13–15]

What foods can support women during stress?

A balanced eating pattern can provide energy and essential nutrients while supporting digestive health, heart health and overall well-being. Aim for a variety of nutritious foods across different food groups. [11, 15]

Types of nutrient Why it matters & food examples
Complex carbohydrates Provide a primary source of energy. Choosing unrefined sources can also contribute fibre. Examples: oats, brown rice, lentils and beans. [7, 15]
Proteins Provides building blocks for muscles, hormones and enzymes. Include a mix of plant and animal sources, such as pulses and lean meats. [15]
Magnesium-rich foods Provide magnesium needed for important processes such as cell function and energy use. Examples: leafy greens, nuts, legumes and whole grains. [9]
Omega-3 fatty acids Play a role in brain and cardiovascular health and in regulating inflammatory processes. Examples: salmon, walnuts, and flax seeds. [10]
Fibre (at least 25 g/day) Supports digestive health. Good sources include whole grains, fruits, vegetables and legumes. [11, 15]
Antioxidant-rich foods Fruits and vegetables provide antioxidant nutrients, while many plant foods also contain polyphenols. Examples include citrus fruits, bell peppers, tea and dark chocolate. [12]

A practical swap: if you find yourself reaching for sugary snacks during stressful periods, try a balanced meal such as salmon with whole grains and vegetables, or fruit with a small piece of dark chocolate. The goal is nourishment and enjoyment, not a “perfect” diet. [10, 12–15]

5 practical ways to manage stress and support your health

01

Move for a few minutes

A walk is a simple way to start. Regular physical activity can reduce stress, support mood and improve sleep. Even a single session can provide some immediate health benefits. [3, 14, 16]

02

Protect your sleep

You can keep a consistent bedtime and wake time, limit caffeine later in the day, and reduce screen use before bed. Adults generally need at least 7 hours of sleep, although recommended sleep duration varies with age. [14, 17]

03

Build balanced meals

Try to include whole grains or other fibre-rich foods, a source of protein, vegetables or fruit, and enough fluids. Aim to eat balanced meals at regular intervals. [14, 15]

04

Notice changes in your eating habits

Stress can cause some people to eat more and others to eat less. If stress is affecting the way you eat, aim to return to regular meals and use other coping strategies as well. [13, 14]

05

Make time to unwind and connect

Try simple ways to relax, such as deep breathing, stretching or meditation. Staying connected with people you trust can also help. If stress feels difficult to manage, consider seeking support from a healthcare professional. [3, 13–14]

When should you speak to a healthcare professional?

Consider professional support if stress becomes persistent, difficult to manage, or starts affecting your daily life. [13, 14]

Speak to a healthcare professional if you are concerned about persistent changes in your periods, severe menstrual pain or possible PCOS symptoms. [18]

Seek immediate help if needed

If you are having thoughts of suicide, seek immediate help at the nearest hospital. [19]
