What Deficiency Causes Sugar Cravings? The Role of Hormones and Menopause

Medically reviewed by Mark Strehlow, MD, Medical Director — September 2026

No single vitamin or mineral deficiency is known to cause sugar cravings. Lists online blame magnesium, chromium or zinc, but the evidence behind them is weak. The better-supported causes are blood sugar dips, short sleep, stress, habit and hormone changes, especially in the days before a period and during perimenopause and menopause. Occasionally, new or constant hunger for sweets is a sign of a medical problem such as high blood sugar, which a blood test can check.

Is a vitamin or mineral deficiency behind your sugar cravings?

Probably not. Here’s what the research says about the usual suspects.

  • Magnesium. The theory is that chocolate cravings are your body asking for the magnesium in cocoa. But in a University of Pennsylvania study, chocolate cravers who swallowed cocoa capsules got virtually no relief, while white chocolate, which has no cocoa solids, partly satisfied the craving. The pull seemed to be taste and aroma, not a nutrient.
  • Chromium. Chromium may play a role in how insulin works. But the NIH Office of Dietary Supplements says chromium deficiency hasn’t been reported in healthy people, and supplement trials show only very small effects on blood sugar and weight.
  • Iron and zinc. These are the deficiencies most often linked to cravings, but the craving is for ice, clay or other non-food items (called pica), not for sugar.

If you’re short of a nutrient, a blood test will show it. A craving won’t.

Why am I craving sweets? The usual causes

Blood sugar dips. Sweets, white bread and sugary drinks raise blood sugar quickly, and it can fall quickly too. In a Boston Children’s Hospital study, men who ate a fast-digesting meal had lower blood sugar and more hunger four hours later than after a slow-digesting meal with the same calories. Their brain scans also showed more activity in an area linked to reward and craving.

Short sleep. In a University of Chicago study, healthy young men who spent only four hours in bed for two nights had less leptin, a hormone that signals fullness, and more ghrelin, a hormone that drives hunger. Their appetite for sweets, salty snacks and starchy foods rose by 33 to 45 percent.

Stress. In a study of 59 women, those whose cortisol (a stress hormone) rose most under stress ate more on a stressful day, and they chose more sweet food overall.

Habit. Sweet food is rewarding, and cravings are partly learned. They tend to turn up at the same times and places: the mid-afternoon slump, after dinner, in front of a screen.

What hormone causes sugar cravings?

No single hormone does. Appetite is shaped by several: insulin, ghrelin, leptin, cortisol and the sex hormones. Research in women suggests that estrogen tends to reduce food intake, while progesterone and testosterone may increase appetite. That helps explain why cravings follow the menstrual cycle and can change around menopause.

Before your period

Food cravings are one of the most common symptoms of premenstrual syndrome (PMS). In the second half of the cycle, after ovulation, women tend to eat more and crave more foods that are high in carbohydrate and fat.

Is low progesterone to blame? The evidence says no. In a controlled trial, women with severe PMS who took progesterone in the days before their periods craved chocolate and sweets no less than women who took a placebo. Research at the National Institutes of Health suggests that PMS is an abnormal response to normal hormone changes, not a sign of abnormal hormone levels.

Perimenopause and menopause

During the menopausal transition, the ovaries make much less estrogen and progesterone. In perimenopause, levels often rise and fall unpredictably before they settle lower.

Does low estrogen cause sugar cravings? It can contribute, but it’s rarely the whole story.

  • Estrogen helps regulate appetite and how the body handles glucose.
  • A Canadian study followed 94 women for five years. Their desire to eat and their hunger rose during the menopausal transition and stayed higher afterward.
  • Hot flashes and night sweats disrupt sleep, and short sleep raises appetite.

Research on sugar cravings through menopause is limited. One survey found that chocolate cravings fell only modestly after menopause, far less than you’d expect if hormones were the main driver. Hormones matter, but sleep, stress and habit usually matter as much.

Low testosterone in men

Low testosterone in men is most often linked with obesity or diabetes, and a direct link to sugar cravings hasn’t been shown. If you have symptoms such as a low sex drive or low energy, it’s diagnosed with morning blood tests, repeated to confirm a low result. Learn about BHRT for men.

When sugar cravings can be a sign of a medical problem

See a doctor if your cravings or hunger are new, won’t let up, or come with other symptoms. MedlinePlus, the National Library of Medicine’s health site, lists these causes of increased appetite:

  • Diabetes, including diabetes in pregnancy
  • Low blood sugar (hypoglycemia)
  • An overactive thyroid, including Graves disease
  • Anxiety
  • Premenstrual syndrome
  • Certain medicines, such as corticosteroids
  • Bulimia

Get checked for diabetes if you feel very hungry even after you’ve eaten and you also have any of these: strong thirst, urinating more often, blurred vision, fatigue, sores that don’t heal, frequent infections, or weight loss you can’t explain. A blood test such as hemoglobin A1c can check. Your primary care doctor can order it, and so can we.

If you think a medicine is causing cravings, talk to the doctor who prescribed it before you stop it. If you often eat large amounts and feel you can’t stop, tell your doctor.

How to stop sugar cravings: what helps

No single fix works for everyone, but these steps have evidence behind them.

  1. Don’t skip meals, and build them around protein and fiber. In a small University of Missouri study of young women who usually skipped breakfast, eating breakfast reduced their later cravings for sweet and savory foods.
  2. Choose slower-digesting carbohydrates. Whole grains, beans, vegetables and whole fruit raise blood sugar more gently than sweets, white bread and sugary drinks. Have sweets with a meal, not on an empty stomach.
  3. Protect your sleep. Adults need at least seven hours a night. If night sweats wake you, raise that with a doctor as a problem in its own right.
  4. Take a walk. In two small trials, a brisk 15-minute walk reduced urges for chocolate and sugary snacks compared with sitting still.
  5. Skip supplements unless a test shows you need one. None has good evidence for curbing cravings in people who aren’t deficient.
  6. In perimenopause and menopause, deal with what’s feeding the cravings. Hormone therapy is an established treatment for hot flashes and night sweats, and the National Institute on Aging notes that managing them may help with sleep. It is not a treatment for cravings, and it isn’t right for everyone. Its risks depend on the type, the dose, when you start it and your health history. Learn about BHRT for women.

How we look for the cause at Rock Creek Wellness

We start with an evaluation, not a prescription. We ask about your sleep, stress, meals, cycle or menopause symptoms, and medicines. Then we test. Our comprehensive blood testing includes hemoglobin A1c and fasting insulin, a full thyroid panel and sex hormones, so we look at the likely causes together instead of guessing.

If the answer is sleep, meals or stress, we’ll say so and help you make a plan. If your symptoms and labs point to menopause or low testosterone, we’ll talk through whether hormone therapy makes sense for you, and its risks. If something needs your primary care doctor, we’ll tell you. Testing is the first step of Premier Care, our comprehensive program. We’re a cash-pay clinic and give you the price at your consultation.

Common questions

Does HRT help with sugar cravings?
Hormone therapy isn’t a treatment for cravings, and there’s little research on whether it changes them. Its established use is for hot flashes and night sweats. If those are breaking your sleep, managing them may help you sleep, and short sleep is one known driver of appetite. We don’t prescribe hormones for cravings.

Why do I crave sugar after a hysterectomy?
If both ovaries were removed, menopause starts right away rather than gradually, so the changes above can arrive all at once. A hysterectomy that leaves the ovaries in place doesn’t by itself cause menopause, but recovery, with less activity and broken sleep, can play a part.
