For new mothers, the months after they give birth can bring profound physical and emotional change. Though these symptoms are widely regarded as normal postpartum, and fatigue, mood changes and body aches can be expected after giving birth, longer lasting signs may in some cases point to underlying nutritional deficiencies. One such under-the-radar issue is magnesium deficiency, which has implications for energy, muscle function, sleep, and mood.

Dr Lavanya Kiran, Director & Lead Consultant – Obstetrics, Gynecology, Robotics, Regenerative Medicine, Cosmetic Gynaecology & Fertility says that Magnesium is a vital mineral that supports hundreds of biochemical processes that keep the body running well.

Some of the vital insights that she point out

1. Magnesium is critical to energy production

Magnesium is involved in over 300 enzymes in the human body, most of which are involved in the body's capacity to generate energy. If there’s a deficiency of magnesium in the body, it can’t pump out enough of the energy that the body needs in order to be active. This leads to excessive fatigue that is disproportionate to how active you are relatively speaking.

2. Nutritional depletion after pregnancy is very common

During both pregnancy and breastfeeding mothers require a larger amount of food to provide the needed nutrients. If mothers cannot provide adequate dietary nutrients to their bodies to sustain the mineral level to allow their bodies to function properly (including magnesium) they can start to feel weakness, headaches, and lack of stamina.

3. It can affect mood and emotional health

Magnesium plays a role in neurotransmitters that play a key role in managing moods. Magnesium deficiency may lead to anxiety or difficulties in coping with stressful situations, which may be misinterpreted as normal postpartum emotional changes.

4. Muscle cramps, body aches, and lack of sleep

Experiencing frequent muscle cramps, body aches, eye twitches, or inability to sleep even if you are extremely tired may be signs that you have low magnesium in your body. These are commonly ignored or attributed to postpartum fatigue.

5. Diet and lifestyle may influence magnesium levels

The magnesium levels in your body may be influenced by your diet and lifestyle. High amounts of processed foods, caffeine and stress could all lead to depleting your body of magnesium. If you are a new mother, you may have extra responsibilities that can contribute to your magnesium deficiency through your eating habits without your knowledge.

Early diagnosis can aid in avoiding long term concerns 

Medical professionals recommend taking note of any irregular symptoms which persist longer than expected following a sufficient period of time spent resting in bed. Ensuring a nutritious diet supplemented with an appropriate intake level of magnesium through natural food sources such as leafy vegetables; nuts and seeds; whole grains; dried beans and peas will assist, among other things, with normalizing your magnesium levels back to appropriately recommended levels.
